Nice benchies

got 2 missing things in device manager which im sure is to do with the gfx card, vivo/rage theatre chip i think.

and in some games i get issues where vpu recover kicks in for no reason, atimag.dll or something is the cause. and vista performance is not at the level of xp performance so wondering if some enhancements to that will be made too.

I dont know mate i dont think i have that at al, will check tonight in device manager but all seemed ok.

Connect 3d 1950XTX x-fire edition, i also found that the vista performance wasnt because of the gfx card but because of the additional load on the CPU
My 3d mark scores when i was comparing them.

Intel C2D E6600@Stock

Just looked in my DM/Other Devices & don't show that with my 1900xtx 1900xt master cards

The 2900xt has the lowest mem so i would really like to see it again with the 1GB version. to eliminate that possibility as thats the res i play at.

it just occured to me, its probably vista not the drivers themselves if your not using the latest cat's.
Press F8 at boot and disabling the forced driver signing, then try installing them

The VIVO drivers are seperate and not included with the Cats.
Driver signing is a major security feature and disabling it certainly isn't recommended.

From what people and techs have been saying is the fact there is no doubt that ATI's solution is more sophisticated as it has the 4+1 Superscaler processors, only problem is its not really translating into real world performance atm unless a big change is made to the way DX/OGL interact with hardware. For a start M$ need to change the HLSL in DX to accomodate the 2900s advanced architecture. We should see advancements in the near future.

you only disable it for 1 boot so you can install the app
I have had to use it for various programs already, Logitech Setpoint for 1

It can get a bit confusing. But its, 4 arrays of 16 stream processing units. Each SPU has 5 way scaler processors. Each of the 5 co-issues floating point Multipy-Add (FP MAD) instructions, but one of the five has a superset for transcendental instructions, like sine cos etc. Take a look at the way VLIW works, you'll see why things slow things down if data has dependencies or the complier has problems creating the instruction word. I'm sure there lots of ways of improving the throughput.

Misssed off the 6, but cheers for clarifying that
