About this build
Performance is close to the assembly-optimized version, although a slight frame-rate decrease may be noticeable. The OpenGL code is affected far less than the software renderer when built in C only.
What I noticed
- It ran at every resolution tested: 320, 512, 640, 800, 1280, and 1600. The downloaded id Software build consistently crashed above 640.
- The game appeared brighter than the build from id Software; the reason was unclear.
Build notes
- The console version string was changed from
(GL 1.00) 1.09to(no asm GL 1.00) 1.09to avoid confusion with official builds. - Built with Microsoft Visual C++ 5.0 Service Pack 3 using default release optimizations.
- Everything else is unchanged except for a few preprocessor definitions.
Use at your own risk. This binary is preserved as a historical artifact and comes without support.
Special thanks to John Carmack for releasing the source.
