Interestingly, I just tried GRS to see if it would help me solve a problem I've been having. It didn't, I'm still getting the same problem, but maybe you know how to fix this...

(Sorry for dragging this thread off topic...)

Back in the days when I was using Windows 2000, before I switched my main PC over to Windows XP, I was able to run Source Engine games (CS:S, HL2) at 1440x1080. This is my current Windows desktop resolution. It's the same number of scan lines as HDTV, but it's the 4:3 width. (1920x1080 would be 16:9 hdtv).

Now, under XP, when I try to make HL2 or CS:S run at 1440x1080, it pops back down to 640x480. Yet my Windows desktop does that rez just fine. And I'm using the same video card as I was using back in Windows 2000 days, so it's not the card at issue.

These games will run at a bunch of different high resolutions, of course, like 1280x1024, just fine. It's something about that particular rez that either Source or DirectX doesn't like.

I also seem to recall vaguely that this problem happens on other directX games, too, not just Souce stuff.

Any ideas, Tom?
