DirectX 9.0c vs DirectX 10
#1
How much of a difference does it make as far as performance goes on PCSX2? What about 32-bit to 64-bit?

If it's as big of a difference as I might hope to see in responses, I might have to just get a copy of Vista64 just to try PCSX2 on it. Tongue

32bit-64bit doesn't impart any performance benefit. But if you're looking for future-proofing and/or have >= 4GB of ram, it's a good idea to get the x64 version.

DX10 in general outperforms DX9 by a noticeable margin. Gabest is actively developing the DX10 portion of GSDX, so that gap is just going to keep on increasing.

All in all, I say go for it if you can get a copy of Vista x64 and your hardware has available drivers. If you're a student at a US university there's a good chance you can get it for a steep discount through your CS department.

Most games get better speed with DX10. I get 10more fps on tekken5 with DX10.

I still get the other result min dx10: 25 and min dx9: 40fps summoning shiva here Tongue

But yeah DX10 will make most games faster overall anyway.

what are your specs? internal resolution? do you use any speedhacks?

On my machine, Gsdx performance in DX9 mode is abysmal, whereas in DX10 mode I can play games at a more than decent speed.
