Quote:4X or 9X SSAA --> You need a powerful video card for this option. Or disable SSAA and set internal resolution to 2x or something. You won't see any major differences. Basically:
1) SSAA: Relies on video card power.
2) Internal Resolution: Relies on CPU power.
WHAT!?!?!?
No, that is completely wrong. Both increase GPU load and only GPU load. When you use SSAA you are increasing the internal resolution whether you realize it or not, the only difference is the SSAA setting uses a box filter to downscale and internal resolution setting doesn't. 4xSSAA scales the x and y dimensions of the framebuffer by 2x each (2 x 2 = 4 times the resolution), 4xSSAA + 1x internal resolution provides the exact same internal resolution as no ssaa + 2x internal resolution. Unfortunately the 4xSSAA shader is still broken. It still renders at the correct resolution but it does not downscale correctly at the moment. Both settings increase the number of pixels your gpu has to render to produce each frame which increases gpu load significantly since pixel shaders need to run over and over to fill every pixel in the buffer. However the same number of draw calls are needed because the same objects are being rendered in the exact same way, just at a higher resolution. Therefore cpu load does not change at all.
A higher internal resolution also increases the amount of memory bandwidth/video memory bandwidth needed depending on which efb copy method you're using. Since the framebuffer contents constantly need to be copied obviously a larger framebuffer will require more bandwidth.

*facepalm*
Please people if you don't know what you're talking about don't give advice. Incorrect answers are worse than no answers.
I'm guessing the OP is using some insane level of SSAA which is causing a gpu bottleneck since that cpu is way more than sufficient for this game. Also OP what efb copy method are you using?
Edit: Already I just noticed you already posted your settings. Yeah, I was right, 9xSSAA is way too high for that video card. Turn off SSAA and you'll have no problem using a high internal resolution.

SSAA was broken in 6549. 4xSSAA should not work properly in 7553. Also it is not a case of shoddy programming, it's a case of accurate efb emulation screwing with the outdated shader. The shader needs to be remade and nobody wants to do it. But the shader was perfectly designed for the old efb emulation.
