Performance issue with ATI X1950Pro AGP?

[nievkNYC]

I have the same problem Radeon x1950 Pro. Really sucks as it freezes the whole PC. MY monitor even turns off when it stops getting a video signal!
I have to hard reset to recover each time.

Started happening only after a couple days of play and then more frequently. I upgraded the catalyst drivers from 8.12 to 9.1 but no joy.

Might try reverting to previous poster's version.
Others mention slowdown as time goes on, I noticed that too. Is there if there is some kind of memory degradation as you get further into game?

I bought it form the Atari site, then upgraded from 1.6b7 to 1.6.5.
Great game, wish I could play it for more than a few minutes.

I really would like to play this game but I get no further than 5 mins before my screen goes black and I'm forced to hard reset.

The window's App event log shows two events that it attributes to kb.exe
Basically the game stops the Windows Desktop Manger from restarting once it crashes.
First event is
"A request to disable the Desktop Window Manager was made by process (kb.exe)"

Second event is:
"The Desktop Window Manager was unable to start because composition was disabled by a running application"

Then there's what looks like a crash event"

Bought the online Atari version, updated to 1.6.5
Vista Premium, all the latest patches
Radeon 1950 drivers 9.1
updated November DirectX
Quad 6600 , 3GB RAM
I even tried setting the process affinity to 1 CPU, no luck.
I sent the dxdiag.txt to support and didn't even get an auto-response.

UPDATE: I since heard from Support and am going through a series of a suggestions.

So my card died, my PC wouldn't boot up.

Switched to the onboard graphic chipset and everything else was fine.

Ended up buying a Geforce 9800 GTX+.

and now I have graphic corruption!

when it rains it pours :-7
