How to boost your Doom III

Simply by editing a file!

Quote:

Save the file and close your text editor. WinRar will ask if you want to update the file in the archive, select yes. Close WinRar and enjoy about 40% higher performance in Doom3

Hadn't tried running a timedemo though. So I did that now, and I'm still getting a large performance increase, though not quite as large. It went from 17.5 to 20.0, so that's a 14% boost, which is still a large improvement. I can see the reason why the timedemo doesn't give the same performance boost though. It's not as dependent on the lighting shader, but depends a lot on the performance of the multiple layers of smoke and fire that those darn monsters are throwing around.

edit: seems people at that forum are reporting visual artifacts, although very small, so it is up to you

If you have an ATI card and don't want to install the 4.9 Beta drivers but would like to enjoy a speedboost, all you need to do is drop the atioglxx.dll from the 4.9beta archive into your Doom 3 folder

I did it and experienced lots of HUGE artifacts. Lucky I backupped the original file.
