Idea to get better performance on slow processors

I've made some testing to see if is possible to render the scene with resolutions below 320x200, with corrected aspect ratio. The main idea is to reduce the number of...

While testing VESA modes on FastDoom I've discovered that DPMI function 0800h crashes if you try to map more than 8Mb. This issue also happens on other games, and it's...

Some newer CPUs prefer rendering functions that fit in the L1 cache rather than fully unrolled ones. I think this will optimize performance in 640x400 and higher resolution modes on...

Multiple sound cards are not working correctly - [x] Sound Blaster Vibra16XV (fixed, works with IRQ 2 and DMA 1) - [x] Gravis Ultrasound (fixed, memory allocation problem solved) -...

Re-enable hardware mixing on Gravis Ultrasound cards

The Apogee Sound System uses software mixing instead of hardware mixing, which is slower but provides more functionality. Add the option to use hardware mixing. > 7/24/95 > >- Changed...
