I never understood why to upgrade memory of any isa video card. They are not fast enough to run anything at higher resolutions that would require more memory. Generally even 512Kb is more than enough for any isa video card. ISA MACH32 was the fastest Windows graphic card in 1992, as in 2 times …

bios modding?

I never had a DX2 and dont quite see why I would go for one instead of a DX4 either There is almost 2 full years between the two, 92-94. DX2 is associated by a lot of people with being a staple of DOS gaming golden years, sweet spot, while DX4 came out as a pleb budget alternative to Pentium 100 …

you will always need full low level chip support, for example nvidia mods https://docplayer.net/24603374-Mods-modular-diagnostic-software-for-nvidia-graphics-products.html https://youtu.be/DG_dyOohSQ0?t=9m8s otherwise you are limited to ram allocated by the driver into usable graphic buffer pool ( …

last release is from 2002 and apparently did support gf2, varrol might also try nolfb 1.Yet, UNIVBE is still absolutely pointless for a GF2. UniVBE was meant for SVGA cards that implemented SVGA resolutions (640x480, 800x600, 1024x768) in a non-standard way (partly because no standards existed) and …

afaik m3d port of Tomb Raider is the best one of all the other accelerated ones (Glide/GLRage) because its not capped at 30fps I think it is capped at 30fps though, because the framerate counter sometimes says 60fps, but the game still looks like it’s running at 30fps. sadly the only way to check …

The m3D is definitely the bottleneck. I'd say it performs about average compared to what I've heard about it. Some games have a bit of slowdown, like Tomb Raider for example, but not too bad. afaik m3d port of Tomb Raider is the best one of all the other accelerated ones (Glide/GLRage) because its …

Sounds more like you are bottlenecking on CPU... K6-2 was targeting extreme budget. 1998 wasnt a good year for AMD. AMD K6-2 400 OC to 506MHz is probably around Celeron 333MHz (almost $100 cheaper in 1998) without 3dnow patches, and still slower than 300@450 with them https://www.vogons.org/ …
