What ultra resolutions do you see that happens (corruption and issues)?
1024x768 is not that high. 1280x1024 is borderline, but 1200x1600 and 1920x1080 are ultra high resolutions. Ironic that people are trying to do it at high resolutions with a older video card that is not up to this performance and older software often were not written with ultra resolution in mind.
Besides that makes things harder is ati/AMD GPUs has much more compatibility issues than geforce series?
Cheers,
Anything above 640x480, if I recall correctly. The thing is that with the DOS games it's not that you try to do high resolutions by using a more powerful GPU since these are all software rendered. The goal is to get the fastest single-core CPU possible - no such thing as too fast for this purpose - with the most compatible GPU. Dropping down to a Geforce 3 fixed the build engine games. On an A64 4000+ at 2.4ghz you get these kind of results... note that Blood's ingame FPS counter just gets whacked out at a few resolutions on a Geforce 3 still but the actual framerates are still good except for the 5:4 1280x1024... that bugs out.
Blood
320x200= 274FPS
640x480= ~60FPS
800x600 = 4FPS ... LIES, feels exactly the same as 640x480.
1024x768 = 24FPS ... more lies.. see above.
1280x1024 = 15FPS ... also lies but certain areas where it dips to 7FPS it feels like it is ~15.
1600x1200 = Locked 50 FPS, totally smooth
Duke3D @ 1600 x 1200 = 59/60FPS locked... perfectly smooth.
DOS/Software Quake
300x200 - 223.1 FPS
640x480 - 85.1 FPS
800x600 - 57.9 FPS
1024x768 - 40.5 FPS
1280x1024 - 41.9 FPS (not sure why but this is consistently higher than the lower resolution)
I'm not sure what kind of machine it would take to run 1280x1024 at 60+ but that machine would probably not even be able to get sound in DOS even with a decently compatible PCI soundcard.
The absolute monster for DOS software rendering is PCPBench at 1600x1200 with 32 bit color.
