How do I check if my CPU is bottlenecking my gaming performance?

post #1 of 6
Thread Starter 
Question arises primarily due to extremely low FPS drops in Guild Wars 2 World vs. World combat. This is the first game in 2+ years that has given my system a lot of trouble at reasonable graphics settings. My FPS peaks at 100+ with reasonable settings during normal gameplay but drops to the 15-25 range while using the lowest preset possible when there are a lot of people on screen in World vs. World.

Folks on the GW2 forums said the above issues are directly related to my overclock. I OC'd my i7 920 to 4.0ghz back in Summer 2010 after I purchased my system and have not really "tuned" it since then. From what I remember, I ran prime95 for over 24 hours to make sure the OC was stable/temps were in-line.

Can anyone think of a good way to test whether the OC is causing an FPS issue? Should I re-run prime95 for [x] hours to recheck my stability?

Any help is appreciated. I feel like a total noob again since I have not done this in so long.

Many thanks

Run MSI Afterburner and see if you are getting near 100% GPU use, if not then there may be something there.

But a i7 920 @ 4.0GHz would not bottleneck a 570.

Few things to check first. Check your GPU VRAM usage and make sure you're not bottlenecked on Vram usage. Once that's clear then check your system memory. I have a feeling it might be system memory. 6GB might not be enough. I know for BF3 its really a minimum of 8GB for me.
Try disabling Aero when you play and see if that helps:
Go to the game .exe file
Right click, and go to properties
Tab over to compatibility
Check the box that says "Disable desktop composition"
Hit ok and run the game

Doing that will put your windows theme to basic, then when you close the game, it'll return it back to your normal setting. This free's up a few hundred MB of Vram and usually a big chunk of system memory as well. I only game with this setting. Give that a try and see if that helps.

Also check your CPU usage in task manager and see if its bottlenecking. I doubt its bottlenecking...

Hope that helps man!

Agreed. A 4Ghz Bloomfield is plenty for a 570.

Thank you for your response.

Couple questions
1) GPU VRAM usage I can check via Afterburner?
2) When you say to check my system memory - do you mean Physical Memory Usage History in Windows Task Manager?
3) Will try disabling Aero and see if that helps

I think either GW2 devs or nVidia's driver team still have some kinks to iron out. My FPS in GW2 varies wildly and sometimes drops to 25 FPS even when not a whole lot is going on. No other game has managed to bring my system to its knees like that, and I really doubt GW2 is that punishing.
I've never seen it use over 1gb VRAM or 2gb system RAM (in fact I've never seen it use anywhere near these numbers) so I doubt you're lacking in either of those.
