Does Vista run this emulator faster than XP?

[dvorak]

Wait does this mean that in WinVista with DX9 it will be slower or would it be just the same?

[Jlagreen]

not only faster, but there seems to be fewer graphical glitches under GSDX10 mode instead of GSDX9(L), from my experience anyway.

not really, it depends on the game. Best result in this regard ist the DX10 software renderer but it is slow on lower CPU clocks and only native resolution possible .

Games look even less pixelated in my opinion

Only Native resolution is possible on Direct3D10?? are u sure?

[Krakatos]

He's talking of dx10 software renderer. And yes, on dx10 software, you can't change internal resolution.
On dx10 hardware instead you can, but some games have the usual problems.

I'm confused now.. oh well idc anymore lol

If you've ever read up on directx 10 architecture you'll find a good portion of your answer for why pcsx2 is faster in vista. Its counter intuitive, vista is supposed to be slower than XP right? Its slower in most PC regular games, even ones that run on Vista's DirectX9L (D3D9ex), so shouldn't it be like that for pcsx2 as well?

One of the big reasons for the rewrite in the architecture that came to directx 10 was it reduced API object overhead and took a number of operations that previously required 'x' number of cpu cycles on the cpu to complete and reduced them or moved them to the gpu, sometimes decreasing the number of required cpu cycles by a factor of 10. Directx 10 is less cpu bound and dependent than past versions of directX. There is also improved cpu/gpu synchronization.

One of the biggest limitations is API object overhead. In fact game content developers are currently being bottlenecked by this overhead. Out of all the improvements that could be pushed into DirectX 10, the issue at the top of the list for most game developers was to lessen API object overhead.

What we mean by API object overhead is that the API is using CPU cycles to achieve tasks necessary for rendering before being output to the video card for drawing. When rendering a game, the application first has to call to the API and then the API calls to the driver before it ever interacts with your video card’s GPU. These calls are all handled by the CPU, using valuable resources and creating a potential bottleneck.

More workload being taken off cpu and placed on gpu is great for many pcsxtwoer's with 8800gt or better, as their cpu's are the bottleneck.

Its not quite as good for pcgamers and it may contribute to why both D3d10 and d3d9ex (d3d9 run through the dx10 api) are slower than d3d9 since in modern games push gpu's to their max.

HOLY SHH111T!! after I installed Vista and ran PCSX2, the framerate got DOUBLED... wow this is amazing... It was really worth it installing Vista. Everyone should use Vista for PCSX2!

You guys have no idea how happy I am right now LOL now I can play all of my 3D games at full framerate!! xD

AFAIK vista been faster or as fast as XP with most DX9 games loong time (with proper system of course).

Vista used to be a lot slower in the beginning, mostly because of crappy drivers...


About DX10 it will prolly never become popular. Many developers may jump directly to DX11 as advantages between DX10 vs DX9 are not that great and because XP is still more popular than vista...

[Summoner]

Vista will not faster then XP. DX10 can boost ingame fps or can slow down, depend of game.
