I was just wondering if my video card is somehow causing the not-so-good performance that I am getting in PCSX 2.
System specs are:
Intel C2D E7300 2.67 ghz
mobo with intel chipset (p45)
2 gb ddr2 Kingston
Gainward 6800 GS Bliss 512 mb
Thanks in advance!
Could be, depends on the game and the resolution you have set in GSdx. If the GSdx title bar reports above 90% CPU usage, it means your GPU is the bottleneck.
Mine shows 99%, always.... ):
You can reduce the load of your video card by checking 'native' in GSdx config. You can also further reduce the resolution (although not recommended) by changing the internalres value in the GSdx.ini file manually to something like 512x512 or lower (it will crash though for really low values)
I'm using native res (512 x 512 looks total crap), no EE speedhacks, no frameskip, default plugins with 0.9.6 stable release. Now that you've mentioned about "90%" cpu usage, I observed the game status bar while playing (GTA: vice city stories) that the slowdown occurs when the cpu usage meter hits on somewhere around 98%.

That explains it ! I wondrered why i have so high load and my brother doesnt, i have gf9500 and he got 9600

Now I understand the full concept of bottleneck...the gfx card is too slow to render video output in comparison to how fast the cpu is processing things, making the cpu repeatedly process tasks it has already dealt with which causes the task queue to fill up and drive CPU usage to almost 100%. I guess the 6800 gs could not keep up with the e7300 then....

Use some speedhacks if you can. You can bump the speed much higher. I can play it on fullspeed(without VU cycle stealing of course) with specs in my sig.
