Cod4 lag... any ideas?

[Sanc7]

So i recently put togather a system that should totally destroy cod4. The first level played fine, but now when i get to levels that are in cities, with alot of smoke and people shooting at me, it drops down to around 40fps or so, even with everything turned down. Ive tried to lower the resolution from what im using (1920x1080) and it still lags. World of warcraft plays flawlessly with everything turned up, As does crysis, but with everything on medium. Any ideas would be appreciated.

Windows XP (64-Bit)
Intel i7 920 (Oced to 3.3)
Asus P6T mobo
6 Gigs of ram
Radeon HD 4890

Have you downloaded the latest drivers for your GPU? Also have you patched the game to its latest version?

Drivers: http://support.amd.com/us/gpudownload/Pages/index.aspx

EDIT: You should be able to play Crysis on high (Turn off AA though, it kills FPS) and I would also get the latest patch for that as well.

Hi and welcome to TSF,
What is the brand and model of your Power Supply?
Also post the amps on the 12v rail.
Aslo could you post your temps in game.
Thanks.

Im actually at work right now. My psu is a Corsair 650TX,(http://www.newegg.com/Product/Produc...82E16817139005) i dont know the volts offhand, and i havent checked the temps yet, considering its not oced, didnt think it would be a problem. I'll be sure to check it when i get home, which should be in a few hours and post up a reply.

Note: When i first put the system togather, i was having a problem with the card. When i would turn it on, it wouldnt post at all, and i would get 1 long beep, and 3 short, which is a graphics error. The GPU fan would also spin at 100%.Asus tech support told me that chances are it was my card not liking my PSU, So i went and got another PSU, and had the same problem. It eventually fixed its self, after i installed a 64bit version of XP. (couldnt get windows 7 to work at all for some reason)

Figured id fill you in with the problems ive had with this setup.

Edit: I just realized i havent updated direct X.. Im guessing that could play a big factor.

[Mart2912]

You say your setup runs flawlessly on World of warcraft but don’t let the games graphics deceive you, it can be a very demanding game.

That PSU is more than enough for your setup(Assuming you only have 1 or 2 HDD and DVD drives) but so far it does sound like a driver issue (Make sure you use a program such as Driver Sweeper once you have uninstalled your current driver before installing the new one). If you have the latest ATI driver I would try to use a previous version to see if that would help.

EDIT: I wouldn’t think that DirectX would play a major part as 90% of games ask you to install DirectX whether you have it or not. If you never saw directx being installed while Crysis or COD 4 was being installed then it just might well be your problem.

I only have 1 HD and 1 Dvd-RW. I've only the newest drivers installed on this system. I'll update direct X when i get home and post an update.

[Sanc7]

K so ive installed the new direct X, patched cod4 with the latest patch, and its STILL running like crap. Crysis runs perfect with everything all the way on high @ 1920x1080. Im beginning to think its my game =/

Why are you complaining about 40FPS? anything below 25FPS will show as lag and 30FPS and above is perfectly acceptable. The game isn't lagging is it?

[Sanc7]

Well when the game goes from 120fps to 40fps, theres alot of lag. You can feel it slow down hardcore. Its definatly to bad to enjoy. Reguardless, with the rig i have, there should be absolutly no lag, all i want is playability.

[Mcninjaguy]

Can you upload a video to youtube and link it here?

[Sanc7]

Not at the moment, im going to bed, gotta way up for work. I set the max fps to 45, and its running pretty smooth, but im pretty sure i shouldnt of had to do that. If somethings wrong i really would like to find out what. =/ Ill post up again tomorrow when i get off.

[Mcninjaguy]

Well if you put on V-Sync it will show the max FPS your monitor can handle keeping it at a steady pace. I can see how going from 120FPS to 40FPS would be a bit wonky but it shouldn't really lag.

Have fun at work!

[Sanc7]

Yeah, I tried to put vsync on, still lagged slowed down alot when it went from 60 to 47-50ish. I just really wish it would run like it should. =( still at work, ill see if i can upload a video when i get home.

[Sanc7]

So i uploaded a video to youtube, waiting for it to be processed, not sure how long that takes considering its my first one ive ever loaded. I used fraps and set the cap to 60 (as high as it goes i guess). In the video, it would stick at 60, then go below even whats normal for my low (around 35ish, guessing because fraps was running).

I just watched a video of someone with 512mb of ram, and a 9600gt playing this game perfectly... i think im gonna puke =/

[Sanc7]

YouTube - I LOVE LAG I dont know a damn thing about using fraps or videos, the fps is pretty blurry, the game isnt as bad as it looks on the video for some reason..

[billypnats]

o.o i played that game with x1950 pro on some high setting and got better FPS =.=

did u try playing at a slightly lower setting? I know that your computers a beast, but if you still lag a lower settings then we know that its a software problem. btw if you're running like 32x AA then its definitely going to lag. go to CCC and see if you have any unneccessary stuff turned on.

BTW that really sounds like a problem with post processing and Flip queue size or max frames to render ahead, try different settings with that and see if it helps

[ebackhus]

Try running the CPU at stock settings. OC'ing can cause problems.

not really sure what that means lol.. And i did run it at stock speeds already, this was happening before i océd it =/

[billypnats]

just a question how long did you have the CPU OCed for?

well for those settings, just search up Ati Tray tools, install and run in the "auto balanced" profile.

Right click on the diamond icon thing beside the clock, go to 3D profiles and select auto balanced. Do it again just in case :D

[Sanc7]

I've basically narrowed it down to Water Detail, When i have it on normal, it lags like hell, even when there is no water in the picture.. Everything is all the way up, other than AA and Water detail, and it perfectly fluid... should i beable to run this with AA and water detail? WD tends to make it lag even with no water..
