Re: C&T 69000 is good for retrogaming?

I've looked into these cards and they are interesting for DOS AFAIK. VGA Museum has some Quake benchmarks, it does pretty well if I recall. Separte cards for the consumer market are rare, you do see them offered as pulls from Siemens / NCR / medical machines, hence there is little info concerning …

I recommend to you, run on a period correct pc first (mostly they are slow - 10-20fps was normal). The normal gus classic also important, the guspnp plays sometimes differently, with different speed, and the demo is timed to the music. The late demos support directly the interwave. Another issue …

And according to https://gona.mactar.hu/DOS_TESTS/ the S3 might just have a slight edge in working with the m3D in Tomb Raider. Is the output of the S3 to your liking …

That's what I first thought, but you are actually right, my other Toshiba Tecra with 800*600 panel does scale to fullscreen. But I've had a 1024*768 Thinkpad that scaled just like this Siemens does. Perhaps it's due to panel size. So do you think it is possible to change this behavior? I am not …

The BIOS will set a 400 line resolution, no matter what you do. No TSR will influence this. I've just checked the CT6554 hardware register document. http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.369.9368&rep=rep1&type=pdf Support for 1024 panels is mentioned, as is stretching. There is an …

Yeah, this is normal behaviour because the TSR preserves the aspect ratio of the original resolution. Afaik, it can only scale neatly between resolutions that are multiples of each other, and since 1024p is not a multiple of 320p, you get the borders to make up the rest of the screen space. Ah, on …

I know FastTracker II uses a 640x400 mode... Perhaps it tries to maintain square pixels or FTII uses some video signal trickery for its timing. Can you try Wolfenstein 3D? It has become my test game of choice to test videoscaling on my videocard.

The BIOS screens will remain cropped as the TSR is loaded after that. Try VEXP M2 to see if that gives you full screen in DOS. Scaling graphics/text mode are seperate functions of the video card.
