First my specs :
 Intel Core 2 4400 processor (x2) 2 GHz each
 NVIDIA GeForce 7300 GT video card (256 VRAM)

The problem is that 9/10 times after a map loads, either a crash occurs, the computer restarts or monitor stops displaying stuff ("No Signal"). The game is patched, well it didn't really happen before the patch ​.

Help please?

it's possible the patch added something your card can't handle, which would be unfortunate. silly questions time:

1) have you got the latest card drivers?
2) can you still run other graphically intensive games that you could run before?

1)Yeah I have all the latest drivers.
2)All other games still run fine, but they aren't that graphically intensive. Maybe Gothic 3 is something close but it runs quite fine.

have you posted this on ut3's forums, wherever they are? they could probably help more, this kind of stuff is quite common around patches.

Yeah I'd do exactly what Jester said and go straight to Epic or Ubisoft or EA or whoever publishes Unreal these days. Check out their technical support forums, chances are they have a sticky detailing your problem exactly.

The game crashes (or freezes with the infinite sound loop) constantly on my machine as well. I think it's just a buggy-ass game.

are you sure man it seems a little weird to have a dual socket motherboard and put two low end cpus in it

Only a week or two ago nvidia released special drivers for ut3, are those the ones you got?

Redownloaded the drivers recently, and it finnaly works. Thanks I guess.
