"capped" fps in DX10

[McScwizzy]

Your system is better than mine, and I run with everything on High just fine. So you probably have some kind of bottleneck going on that can be fixed.

Have you tried the following:

1) Try using Directx9, and install CCC for Warhead.

2) Try turning off one of the SLI video cards. Crysis is tuned for SLI/Crossfire, but this is a problem on many games.

3) What map are you using as your benchmark? Kagoshima is a beast, and ruins even the best systems. not the best choice for a benchmark unless you are the only one on the map.

4) Double check to ensure nothing is gobbling up resources running in the background. Antivirus, punkbuster, etc.

5) Defrag the hard drive?

1. I have been using DX9 and was using the CCC for Crysis which was versions 1.31 I think. I did not know there was one for Warhead, I'm thinking that was the problem. I installed that version which was 3.0 selected High settings and the Realistic shadows set my resolution for 1366x768 (don't ask, my HDTV is weird lol) I got on a server with about 24 people and I didn't see it drop below 30...I think it might have did the trick. The map I was on was Palisades, but I got into a pretty big fight where it was about 6vs6 lasers, lrms, and ppcs flying everywhere. It normally would have easily dropped into the low 20's. I am scared to try other maps though lol. Hopefully, this did the trick.

2. I have tried turning off SLI. I have even went as far as taking it out of my PC, and it had no effect whatsoever.

3. Kagoshima is the map I have been using a lot to see if there was any improvement that could have been the reason, but then again I was on other maps too and it did the same thing.

4. There is nothing gobbling up my resources in the background. The only thing gobblin up my resources was Crysis.

5. Defragmented my hdd's a couple of nights ago.

I will have to do some more thorough testing, but I am thinking that it was because I was using an older version of CCC and that is the reason I was seeing no improvement. There must have some newer configurations on the autoexec file.

Ok so I was wrong, got on thunderift and still dropped into the low teens:/ I guess it is a lost cause lol

I just realized you're using an HDTV to play games. Whats the response time on that thing? A poor response time will kill your perceived frame rate. A game will report 40fs, but it will look so much worse because the screen doesn't actually draw fast. Does it get worse if there are fast moving objects on the screen?

Have you tried it on a normal LCD monitor?

A friend tried hooking up his HDTV to his PC and had similar issues.

[SquareSphere }12thVR{]

Yeah i'd just plug into a normal monitor to just make sure your system is running best as possible.  The type of HDTV affects it as well.

[McScwizzy]

The response time is 8ms, I don't have problems with other games. It is only this game that I have trouble with, I just got this HDTV a month back because my monitor took a sheeite and and I was wanting to get a new TV also so I got a Vizio 32".  Around 40fps it is very smooth and when it drops to low teens it crawls, it is about the same as when I had my regular monitor a few weeks back.

[McScwizzy]

I do recall not formatting after I upgraded from the old 8800 gtx's. Could this be causing a conflict if there are reminents of the old vid card drivers in the os or registry?

[McScwizzy]

I have reformatted and nada. I have set my cpu back to stock speeds and took the other card out and STILL the same frames no matter what detail. There has got to be simple solution that I am overlooking here.

[~SJ~ Wolf]

Do you have V-Sync checked? If so turn it off.

[McScwizzy]

VSync if off, that is the first thing I checked.

I seemed to have solved the problem, I turned Threaded Optimization on in the NVIDIA control panel and it seems to have gave me a pretty big boost in performance. I was playing everything on High on Kagoshima and it didn't drop below 19 amazingly and on other maps I only saw it drop to 25. It is kind of weird how something as little as that made a difference. I am still stumped on why it would though.

i dunno man.....that is strange...i wonder if it's not a motherboard bandwidth issue....or could the power supply be starving them for power.....they might not have enough juice to switch from the low power desktop profile to high performance mode

Just to make sure I checked the clock speeds on the desktop and in game, and it does switch from desktop to performance mode at the correct clock speeds, so it is getting enough power. I was thinking the same thing it could possibly be a bandwith issues. I got an EVGA nForce 780i SLI FTW motherboard so it is not like it is a cheap knock off brand. I am wondering if I am missing a BIOS setting somewhere.

[GB-72AT Talon]

Could the PCI-E bus speed have gotten changed to something other than 100mhz maybe?  Or could the slot be running 1x speed?  Seems unlikely...  it also seems odd to me though that you get the same performance with SLI as with one card....that's just not right..

[McScwizzy]

I have checked the bus speed it is 100mhz, I was thinking about moving it higher, but I am not quite sure of the adverse affects if I change it. I have it set on auto, maybe I should manually set it at 100mhz. The BIOS could possibly be changing it dynamically.

i guess its possible but i doubt it

you wont get much out of it although the performance benefit is somewhat large....a few Mhz bus speed is quite noticeable on synthetic benchmarks like 3DMark...but cant say what happens in real world play.  back when i was into hardcore benchmarking it was my "secret weapon", people couldn't figure out how i was out scoring them with the same setup....LOL 

dont be alarmed if you crash at 103Mhz...some cards i have had cant really take any increase, but i think it was a 7900GT that i had that would run 110Mhz....

at any rate i do not think thats the problem....but i also dont know where else to look yet....

i will suggest you come on over to http://www.hardocp.com/ and register in the forums and post your issue there in the video card section.  tons of people online at once there, tons of nerds like me, probably the most active and informational place i know of

Ifremoving a card gives you the same fps as is with sli, then you do not have sli working. With two gtx 580 the difference in fps is pretty damn noticeable even on 1920*1200.

While my huge fps drops was because of my now dead cpu, sli still worked even then.


I would suggest you make sure your cpu isn't playing silly buggers, and that sli is not only set in cfg but working also.

Window mwll while running if your fps does not change at all then either your cpu/graphic cards/software/drivers are screwed.
