DOS ain't dead

UX with nVidia GTX 970 (Users)

Hi,
I had a chance to test a nVidia GTX 970 card under DOS. My short tests led me to assumption that the VESA BIOS has the same bugs like on older GTX 670 - e.g. problems with Dark Debugger, crippled fonts in Keen Commander, a bit messy graphics in Partition Magic...
VESA mode list seems to be built dynamically according to attached monitor (it's EDID) trying to utilize a native resolution. I tried 2 LCD panels, my NEC via DVI-D with 1600x1200 - it was the max offered VESA mode, total 31 vmodes. Then I tried with Dell 1900x1200 via DP and the max offered VESA mode was 1900x1200, total 35 vmodes. The xfer speed in vesatest was cca 2,8GB/s same as with GTX 670. So there seems no differences in VBE implementation on this nvidia cards. Maybe it helps someone upgrading his system (GTX 9xx is the last line supported in WinXP-x86).

DOS gives me freedom to unlimited HW access.
