CPU limited or GPU limited

[Nokiaman]

Some people say it's CPU some people say it's GPU.What is it?

[Bositman]

GPU most probably.You can test that by using a lower internal resolution and watching if the FPS drop or increase.If the fps increase with the lower res,it's your GPU.
If the FPS stay the same,it might be some of those games that stress GSdx so much that in the end the game is again CPU limited

The CPU usage displayed in the window is always and only your GPU usage. It is possible to have that CPU reading be 10%, and still have a game emulate slowly (other 90% in use by the CPU emulation).

your graphic card?


from my experience most PCSX2 games are CPU hungry
a 8800GT can run easily Tekken5 on an overclocked C2D while it can ran very slow on a CPU like amd's x2 6000+

My GPU is ASUS EN8800 GTS 512MB and please don't bother me with AMD.

Nokiaman, you didn't specify your CPU. Your video card is fairly decent, so I'd imagine you're CPU-bound.

Unless you're running something really old like a radeon 9800 (some years old) OR you're running at extremely high internal resolutions with AA, you're almost always going to be CPU limited. Bositman has suggested ways to test for this.

With the game I'm playing right now, I'm definitely CPU-bound as changing the internal resolution in Gsdx has 0 effect on my FPS. Overclocking, however, changes things.

Well he has new G92 8800 GTS.

Probably your CPU is not enough fast. Overclock to 3 GHz or above if you can

AMD are ftw!, bar the CPU's that is xP, they'll get better i sware!

[Nokiaman]

My CPU is AMD Athlon X2 6000+ overclocked to 3.2Ghz

Then it is your CPU, as much as i hate saying it AMD chips arent as good as intel.
