As a sidenote, there's a bug with at least GF3 and GF4 cards, either of which would be a natural choice in a P4 DOS system, that produces a really annoying flicker in the bottom of the screen in Build games at 1280x1024. You might want something else if that's your target resolution. No idea if it applies to higher resolutions aswell.

There is a fix for that. If you use the NOLFB utility, it will fix the flickering issue and boost frame rates: NOLFB - Disables LFB enabling DOS games to fallback to VESA 1.2 modes

When combined with FASTVID it yields the best performance at higher resolutions with Build games.

It's kind of wild how disabling Linear Frame Buffer support and forcing a fall-back to bank-switched video memory access actually yields better performance.

I'm impressed with just how much of a performance boost it enables. Between NOLFB and FASTVID, I got a ~70% FPS boost at 1024x768.

I just got my kit together save the Pi Pico. Still need to pick that up, but I am looking forward to working with it.

I hope you post your results once you get it put together. Really curious to see how the Throttle Blaster performs in different setups. 😀
