LOW FPS in CS:S

I have the following specs

3.2ghz phenom ii 840 quad
asus 560ti
antec neo eco 520c
asrock 880g-le
4gb kingston ram

When i play counter strike source, i often get over 100 FPS but i also get very close to 60 FPS at times. Lowering the graphics barely helps in this regard. For such an old game i expected this to run flawlessly. Any ideas?

  1. 60 frames per second is very good. Not sure there is a problem.
  2. when i had a 6870 with the same setup i would never go below 200fps. Something weird is going on for sure, i should be staying well clear of that 60 mark.
  3. Those FPS are outstanding. You won't notice anything above 60 FPS so I would enable V-Sync to save your computer's resources.

    Why don't you tell us how much VRAM you have.
  4. The Source engine is very finicky. With my HD5870, I am almost always at the 300FPS cap in the benchmarks and normally very high in TF2, HL2, CSS etc.

    But you could have a setup that it doesn't like as much. And honestly I do notice that nVidia GPUs tend to get performance drops from updates more often than ATI GPUs.
  5. 1gb ram on the 560ti. It doesn't affect my gaming was just concerned there was an underlying problem, thanks for the help. Whenever i quit source i get greeted with a message saying the source engine is not working shut it down blah blah so maybe it is software related.

    Right click on CSS in Source, then go to Local Files and have it Verify the cache. Might fix that issue.

    As for that fixing the performance, as I said before nVidia cards tend to get performance drops with some patches. Have seen people with GTX580s getting less FPS than my HD5870 which is not as powerful.
  7. wow just verified the game cache and de fragmented and now not getting anything under 100 and usually no less than 120. Only just installed windows 7 on this computer so didnt think it would have much effect. I also disabled windows aero in the graphics settings (not quite sure what that is) so they may of also helped.

    And i can definitely feel a difference. Although people will say there is no difference is response from 60fps to anything above it, I definitely feel there is. Thanks everyone

    Windows Aero = more VRAM usage.

    Now the mod can close the thread :)
