Unreal Crashes during gameplay...

[Ikaros]

I'm still using the Nvidia 180.48 drivers. In my case I'm certain my game freezing problems were heat related. Since I've been keeping my case and fans dust free and forcing my 8800GTX fan on 100%, I haven't had any lockups if I can keep my card under 80c or so. Im monitor my CPU temp using the EVGA precision utility in my Windows taskbar system tray and it also displays on my new G15 keyboard LCD so I can watch it while in-game. When my PC is idle the GPU sits at 59-60c and playing UT3 it warms up to 79c. Also turn on Vsync to keep temps down too, but it caps your FPS to 60 max but thats okay it doesn't affect my playability. My temps go a lot higher in-game if I turn Vsync off because the higher frame rates heat things up and then things get unstable. BTW my 8800GTX is factory overclocked an extra 25mhz but even when I tried unclocking it the intermittent freezes still happened after about 3 consecutive games or so (when temps got as high as 100c and experienced graphical glitches) until I tried to keep the card temperature down below 80c. I could do better by adding some extra cooling fans and mod my case a little, but that is a future project.

Hmm I just started playing the game again a few days ago and my 8800 gets up to 101c when in game. Haven't had any problems yet, will have to see if paying a few hours is bad for it. I dread the summer though, and the fan is so loud at 100% I'm afraid I'll wake the person in the next room up lol.

Repeat........The latest official Nvidia drivers crash UT3 in Warfare mode......roll back to the previous drivers and all is good. (180.48)

What he said. Rolling back helped another guy in the Troubleshooting Section.

The 8800gt and 8800gtx cards are notoriously hot-running. My 8800gt-oc would get into the high 90c's unless I ran the fan at 80% using Riva Tuner. At those temps I would start to have graphics glitches and occassional freezes. My current EVGA GTX 260 rarely breaks into the mid 50c's at the stock fan speed. Helping is that I have a much better cooling case now (Antec 900).

Mine idles at 70c. And I have it set to up the fan speed as it gets hotter. So when I'm playing ut3 the fan is at 100% and yet it gets to 100c. Anyway next computer I get is definitely going to have water cooling.

[Ikaros]

At 100c (with you GPU fan at 100% too?) I'm surprised you don't get artifacts intermittently. Get a can of dustoff and give everything inside a good once over which should improve things like it did for me, and maybe add a fan or slot cooler for now.

Most people find important only the CPU the VGA n the amount of memory tbh.A good PSU ,quality memory, good ventilated case n more, are not of much importance.THEY SHOULD BE.Dont just buy ready made offers.Ask if you dont know.Many forums n many guys can help you build a BALANCED(very important) n probs free PC based on the amount of money you can spent.

At the beginning i had some issues to with warfare maps (torlan,....) glitching and stuttering near the bases.
I downgrade and upgraded the nvidia drivers and since then i have no problem anymore.

Only once and a while a "close program" and then i have to restart UT3 again.
IMO that comes from the unreal engine versus Vista which makes a calculation mistake...somewhere, somehow...
