The framerate limit removal will be selectable, not all PC can handle more than 35 fps. Similar to other ports, this will use the same 35 tick/second base with interpolated frames to mantain demo compatibility. This mode is also designed for fast 486s (100MHz+, VLB or PCI) and similar perfomance …

So then it seems an issue in the DOS32A 32-bit extender, or an incompatibility between it and SBEMU. I'm going to try your settings on my laptop and the eBox, and see if it behaves in the same way. Thanks Baron for testing! 😄 EDIT: It works on my HP Compaq NX7300, but as you said, it crashes when …

Any chance of multiplayer support being reinstated in the future? Would love to do a death match with 386’s. Don't think so, we gained some fps after removing this feature, and the codebase underwent significant modifications following the removal of the multiplayer. Nevertheless, any developer can …

I've uploaded a new bugfixing test release (just VESA HighRes fixes). Also I've added support for banked VESA 320x200 direct rendering. https://github.com/viti95/FastDoom/releases/tag/0.9.9_test2 I want to do more changes but for now this is to check if everything is working fine. For example, pixel …

Bug reports you say? At first, using the direct rendering builds, I saw flickering (looked like different brightnesses?) on the uppermost line of the status bar; the backbuffered ones had straight up garbage there instead. Saw this across multiple runs at different resolutions... can't reproduce it …

2.0? So with linear frame buffer support? Does it fall back to bank-switching on cards or video bioses that don't have that available? Cool either way, though! :slight_smile: ... EDIT: I've added support for banked VESA 320x200 direct mode, as the 320x200 framebuffer fits in a single 64kb window. …

Wondering if one could find a card with fast 800x600 VBE 2.0 and then stick it in a low end 386, turn it to low detail at 800x600 and have faster fast doom... guess it don't work like that. I have 386DX-40 @ 45MHz with Diamond Speedstar 64 ISA (Cirrus Logic CL-GD5434, 2MB), supposedly fastest ISA …

This is very exciting news. This means FastDoom will work on many modern DOS vBIOSes which have removed all sub-640x480 VGA modes! Many "modern" systems have been terribly crippled by removal of all VGA modes. This means no 320x200 games will run on them in bare metal DOS, but now FastDoom will, …
