When running CFS2 under Win XP Home, I'm seeing a degradation is frame rates over time from 77 fps  to as low as 4 fps as a mission progresses. This occurs in missions with lots of AI aircraft and usually takes a while before it becomes noticeable.  In QC or missions with only a few AI aircraft, this degradation doesn't seem to happen, or it is so gradual as to not be noticable (77 to 66 fps consistently).  Changing scenery complexity doesn't have much, if any, effect. I think the problem is in XP. Does anyone out there have any ideas what could be causing this??

Hugh, gonna need at least a few system specs in order to help you out. How much RAM, Vid Card installed etc.

And let me ask this. In those missions where there are a lot of AI acft. and you experience fps degredation, do the fps go back up when the AI fly off or get far away?

Well, you got a strong enough system to run it in although I know very little about XP. Wife has it and no likee. But am learning it and gathering info for tweaking it.
First, I am going to ask one more thing. Do you have a good sound card installed or is it what come with the computer? If it's what came with the computer, then it will be the integrated sound which ain't no good for gaming. That small bottle necked integrated sound system still has to process some intensive sound and just gets behind, soooo, everything slows down to wait for the sound to catch up.
When I fist installed CFS2 about 2 1/2 yrs ago, it played very slow. Went and got a nice Vid card and more RAM. Still played the same. If I remember right, it was the same thing as yours, but started out just barely ok and then went to worse.
Know what it was? It was a sound issue. Bought a Sound Blaster Live X Gamer sound card and some decent Altec Lansing speakers and no more problems.
I have had others tell me that they have put a good graphics card in and have plenty of RAM, but no sound card and they too have trouble. I guess, just through dumb luck and little history, I have come to realize that CFS2 is ALSO a sound intensive card. I bet CFS1 would play fine on your machine. But CFS2 won't. That's what happened with me and my wifes XP will play CFS1 fine with just integrated graphics and sound and not much RAM. CFS2 is a whole different story.
I suggest that if you are using the integrated sound system that came with the comp. that you go buy a Sound Blaster or Turtle Beach sound card and some nice speakers. Makes gaming and music so much nicer.
Now Sound Blaster will cost a tad more as they have all the "Extra" stuff such as the sound effects and more. The Turtle Beach cards generally cost less because they don't or at least have cards that do not have the "Frills".
Either is relatively inexpensive.
From what I can tell, a sound card is all you need.
Hope the info helps and good luck to you. Keep us posted as to how it turns out.

Just as a matter of interest, Fireman.

I have a pretty low end Compac - 766Mhz, 192 Mb Ram, Intergrated Intel graphics and, surprisingly, a Soundblaster which is the only decent component that came with it.
I have the same problems as our friend in so far as, when playing CFS2, the game gradually slows to a point after 2 hrs or so where it can't be played.
It handles a good load and amount of AI and scenery to begin with but declines as time passes.
However, if I start the game again, a short time after, it is still slow. I have to wait a couple of hours to get the best speed back.

I know this is mainly the intergrated graphics, but I also realise some more RAM and more powerful processor would also make a difference.
I'll update when the time (and the finances) are right.

With regard to the sound card issue, though, I use a P.C. at work that is a bit more powerful than mine (1.4 Ghz 256 Mb Ram Rage pro 120 BUT it has NO sound card at all. I get a message everytime I install that I have to play without sound.
This machine handles CFS2 all night long (12 hours) without a breather, at top settings, and has frame rates and graphics that I only dream of for my P.C.

So it was always my assumption that the quality (or lack of) a sound card wouldn't affect the performance. I suppose, as you say, it depends on a lot of things.

If I had your P.C. Hugh, with all that power and ram and the 64mb graphics card (compared to my intergrated card which "boasts" up to 11 mb from total system memory), I would be extremely uptight if it didn't chew up CFS2 and spit it out, without effort.

That's only my lowly opinion based on the fact that, as I said, the P.C. I use at work will go all night on full settings, and has only half the power of your PC and a less powerful Graphics card.

Hope this sheds some light or helps with a comparison to refer to. I hope I haven't completely confused the issue............lol

Thanks for the info and suggestions Mate. I'll definitley take a look at your Page, and get that Cacheman.

My biggest problem, I think, is RAM. 192Mb just isn't enough when I'm trying to run an integrated card with it also.
The reason I haven't installed more RAM is that I have had trouble finding the right strips. They are a "special' type for mine. But I can get them now , they're just a bit pricey. As soon as I get 384 or 512, I think I'll be fine as far as CFS2 is concerned.

I think the Intel Graphics card I have (82810E) is not bad for what it is. It's true that it does stop me from running well at high settings or with heaps of AI, but if I want to get a screen shot or some thing like that, the frame rates don't matter.
I'm still trying to figure if it's worth $130 to get a Geforce MX440 or similar and the extra RAM and have my CFS2 going really well (especially after some serious tweaking), or waiting till I get a bigger PC because I don't know how CFS3 will run with this PC and the above improvements.
But then, I suppose I'll have the Geforce to go with whatever bigger system I get the PC man to "knock-up" for me.
(I've told the Mrs if she even mentions the word "package" in front of me when we are considering a bigger PC, I'll throttle her...........lol) I'll get the local PC man to build one to suit OUR needs and utilise what I already have that's useful.

Thanks Again 

Fireman-
I just downloaded your "Tweaking Guide" and it looks like I have my work cut out for me this weekend.  So far, with all the other things we've tried, the frame rates have improved (stayed a little higher), but the degradation keeps occuring.  I might see if Cashman can help. I'll also try some of the other suggestions in your "Guide"...  And the saga continues.  I do apprecaite the help.

Sorry Fireman,

Haven't been back to this page for ages. I've been a bit busy setting up a web project over the last couple of weeks (and I've still got a ways to go!...... ).

Thanks for the link to the TV site - Interesting!

I'll be doing something similar when and if I ever get to actually update. I'll have the PC bloke that has a shop near me (good bloke, good advice, good prices), make up something to suit both my gaming and web business needs. (It'll probably end up twice as good and only half the price of a "similar" package.
As far as the packages go that the PC companies put together over here - they should be shot for the lousy graphics cards, sound cards, chips etc that they use.
They advertise their "great new Powerful" home systems for nearly $3,000 and all you get is,......say, a low end GeForce (no more than 64mb maybe even only 32mb) with 256 Ram and they make it sound like it's the greatest 'package' ever put together because it has a large size Monitor and 40 or 60 Gb hard drive.
I know some people need alot of disc space but some people (many I know) think it's the rod by which to measure what you're getting!
I've never needed anymore than 10 Gb of space for both my business and gaming needs and I don't recall seeing a so called 'package' with less than 20 lately (and that's usually with integrated graphics and only 128 Mb Ram). They're still asking $1600 or $1700 for it, and people are paying it too.

I wonder why they seem to think that disc space is the most important aspect, to the point where they make it stand out as the "BIG" selling point.
Do they do the same thing there? Or in the UK. Or are we the only 'suckers'........lol

Hey Fireman,

I also had a read of your tweaking guide.
It's very good. Thanks for taking the time to do it.
I haven't seen all of your page, but I'll get to it as soon as I get a spare moment.
All I have to do is get a graphics card now, so I can do all that tweaking............lol
I think I will go for 64Mb GeForce, I can get one for about $120 (maybe cheaper 2nd hand if I can come across one). That, and some more Ram, should get me somewhere up where your quality is.

Thanks Again

Just call me Mr Squirrel. I'm an inveterate hoarder. I had most of SimV backed up at one time, not that I could find a specific file if I need it. LOL
I also have FS98, 2 versions of CFS1, FS2000 Pro, 3 versions of CFS2 & FS2002 Pro currently installed. I use them mostly for troubleshooting. FS2004 beta alone is 4 GB but will not run properly on my old 3d card.

I hope he manages to sort his problems out.

Hey Fireman, I install the Cacheman and seeing as though I'm a 'Neanderthal' when it comes to understanding these things, I used the 'wizard' to set all the options for me.
I'm just about to see if I'm able to run my CFS2 on a higher graphics level or see if I last longer in an 'AI intensive' mission.

I'll let you know what sort of difference I notice.

Thanks

Hey

I have a couple of recomendations for you but first I will tell you what IM running on the computer that I built. I prefer to have Hard Drives, Mother Boards and Ram that has been on the market at least a year. Time and use is the best test for quality. In other words I do not go out on the leading edge of technology when it comes to those parts. selecting a good case is very important. You need good air flow and a case that does not create a vacum on the inside(from Fans). aluminum cools the best. Im not interested in pretty, or being cool. I run my computer in my buisness as well as for gaming. I do not run scuzzy.

Intel Pentium 4 Mother Board_D850MV_ 2 gig Processor

1 Gig_4 sticks_of RD Ram at 35 NANO SECONDS

Stepping 4 on 2 sockets,

Nvidia 4400 (128Meg) Video Card

CDR, CDRW, DVD, 3.25 drive

Internal drives_ 4_ 120 gig 7200 RPM Western Digital Hard Drives

1_ ATA controller card. Kingwin 436-4 aluminum case case

PC Power & Cooling 12 Fans, 850 to 1000 Watts, 12 to 30 Amps Max to the Processor/ Pentium 4 requires a minimum of 12 amps. Power is the key, you wouldnt put a lawn mower engine in your car and expect to go very far. you wouldnt drive your car with out coolant in the radiator.

XP_Pro The reason I picked XP_pro you can run NTFS instead of Fat 32 operating system. Less hard drive space and faster processing times.

If you are going from windows 95, 98 or Mileninium to windows XP or XP_Pro it takes some time to get use to. How ever the flight simulators from Microsoft will run with no problems. But you must install all the up grades for the operating system before you load any programs. Load the operating sustem and test it for a few days. Then do your up grades, then start loading programs ONE AT A TIME. Load one at a time and test it a few days before proceeding any further. You will save yoruself a lot of work and time. 

Bose speakers, no sound card, I left the wires off the mother board, better sound, I have the sound set up to run digital, the sound is much better and it will help keep your mother board from bogging down your system.

2_22 inch View Sonic Monitors

CFS_1  CFS_2  FS98 & FS2000

I run 45 to 1250 frames per second with 4 to 30_G

I also have a lot of addons, custom sound files AND FLY STOCKS AND SUPER MODS.

Graphics and sound will slow your system down more than anything else. If you are running 3rd party scenery if it is not constructed correctly it will SLOW DOWN THE FRAME RATES. I only use certain parties scenery. Remember quality is always better than quantity.

I do have a lot of modS, sound files, SCENERY and TEXTURES My frame rates drop to 35 frames per second. Especially when you are flying 20 feet off the deck shooting at aircraft and the rounds are hitting the water and you have 120 aircraft in the air with 22 ships and counless anti air craft guns, and you are firing 8_50 cals at 175 rounds per second/ dice at 24 with a muzzle velocity at 2150 feet per second, muzzle flash is set at 2 and all sound files are modified. OUCH_LOL

I always change my DP files, Tracers I have 100 percent out of one gun unless it is a coarsair, they did not fire tracers, The other guns reguardless how many or rounds per second they fire do not have trace rounds. If you are flying a mod or a super mod tracers can and will crash the program.

1. disck clean up

2. defrag your hard drive.

3. Check your system resources you should be around 83 to 94 percent free.

If not free them up or do a clean boot. If you are not sure check with the mfg or read your help files in the windows operating system.

4. Buy 2 cans of oxygen and clean the inside of your computer including fans. Heat kills frame rates. should be cleaned once a month.

5. Purchase some plastic conduit. I ran all electrical wires thru the conduit and routed the wires along the sides of the case. No wires in the centre to disturb air flow, this dropped my internal tempretures from 92 degrees centigrate to 78 degrees centigrate. You can purchase the conduit at hardware or automotive parts store.

6. If you are running Intel board go to www.intel.com

7. Download there monitor, it will give you system information, Power usage and Internal Temps.

8. I also purchased from PC Power and Cooling an internal temperature sincer. alarm goes off when the internal temp reaches 95 degree F. I have yet to set it off.

9. If that does not work. Open the case pull out the RD Ram. Check and make sure the Ram is same MFG, Part Number, and nano seconds. You should be between 30  to 45 nano seconds.

10. If you purchase more ram make sure all your ram comes out of the same box. In other words if you have 512 meg on 2 sticks and you decide to go to 1024 meg = 1 gig. You have to purchase a full gig not a half of gig.

THIS IS CRUCIAL. THE LOWER THE NUMBER THE FASTER IT WILL PROCESS. BUT FIRST CHECK AND SEE WHAT RAM YOU NEED FOR THE PROCESSOR and mother  board. CHECK with the board mfg, you can usually do this on there web sight. THE NANO SECONDS is crucial. you will need the Part Number off the Mother Board. You can get this off the mother board itself. See White Tag, You will need a Magnifying Glass to Read It. It should be by the Battery.

11. IF THAT DOESNT WORK THEN I WOULD LOOK AT PURCHASING A DIFFRENT VIDEO CARD. NVIDA, I HIGHLY RECOMEND. THEY HAVE VERY GOOD TECH SUPPORT.

12. IF YOU PURCHASE RAM IT IS BEST TO KEEP IT ON TWO STICKS RATHER THAN 4 STICKS but that gets very expencive.

Just some ideas that might help you or help someone else with low fram rates.
