1117621 2010-07-10 11:06:00 I'm having problems with bad performance in some games, and it seems like my PC just isn't running as good as it should be.. maybe.

Just tried playing Crysis. Resolution 1152x864 on medium settings, no anti-aliasing and v-sync disabled, and it was lagging.

But it was weird lag, not just continuously low frame rates. It would lag for a few seconds, then speed up, then lag... it's hard to describe

I checked CPU and GPU utilization which was 50% and 40% respectively - so if the game is using only half of my system resources - why the weird lag problem?? (And yes, the video card was running at full speed and not stuck in 2D mode)

I don't have the fastest PC but I thought it wasn't too bad:
Phenom II 945, Radeon HD5770, 4GB DDR3 running on an MSI 790GX-G65


Does this sound like typical performance for this hardware? Because to me it seems that something is wrong...

1117622 2010-07-10 11:28:00 maybe your power supply is on the fritz?
Maybe you need to twiddle with your setts more?
I found a nice setting for l4d2 finally that gives me little (if any) slowdown, whereas countless setups i tried before now gave me anything from drops in action scenes to constant 6 fps slideshows.

1117623 2010-07-10 21:16:00 How much free HDD space is there on the drive that is providing the swap file / virtual memory? Sounds to me like cache swapping delays.

How much RAM do you have?

I have about 180GB free on the C: drive, and 4GB of RAM

The HDD light isn't even on after the game loads, so I don't think that is the problem.


Crysis did have performance issues though.

I'm getting issues with almost everything else though too.

Furmark: 63FPS (apparently) but would 'stutter' every 2 seconds or so

Passmark benchmark: Showed my PC as being up to 47% slower than another benchmark with the same CPU and Video card (and a slower motherboard)

I also tried 3DMark06, but couldn't get the score because the stupid thing woudn't submit online.


I've just installed a fresh Windows 7 onto another drive, and I'll do the benchmarks again, see if it's software or hardware....

1117626 2010-07-11 03:37:00 Installed fresh Windows 7, installed latest drivers for everything...

On PerformanceTest 7.0, CPU speed has seen a slight improvement, Memory throughput has increased substantially and 3D graphics performance is also much better (eg: 17 FPS vs 85 FPS)

Strangely enough 2D performance is apparently far worse, but this might be some side effect of Aero(?)

FurMark is also running a lot smoother.


I guess there is something seriously wrong with my drivers on XP, don't see how memory speeds can be affected by that though!

Are there any good and free driver cleaning utilities around for the newer drivers, I think I need to give that a try...

1117627 2010-07-11 06:38:00 Crysis running on Windows 7 was much better.

Don't think I'll ever find out what the problem was, though.

I forgot to Un-Hibernate my Windows XP before letting Windows 7 get permission on my XP drive. Result: Trashed filesystem.

So now I'm recovering my XP files with Filescavenger, and will reinstall the whole damn thing.

Hopefully that will also fix the performance issues as well!

Erk! I'm glad I learned that from you and not the hard way...

1117629 2010-07-11 21:58:00 Could be something such as Anti-Virus interfering? Chilling_Silence (9)
1117630 2010-07-11 22:32:00 Yeah, have you checked that windows firewall isn't blocking some aspects of Crysis? icow (15313)
