ioq3-renderer-bgfx
This is a renderer for ioquake3 written in C++ and using bgfx.
Goal: Make Quake 3 Arena and derivitives look slightly better on a modern PC without content replacement. It doesn't need to run at 600fps, trade some of that performance for visuals.
Status: Work in Progress. Not widely tested. Q3A and TA more or less look how they should.
Features
- Anti-aliasing - MSAA, SMAA
- Soft sprites
- Real dynamic lights
- Extra dynamic lights for Q3A weapons - BFG, Lightning, Plasma, Railgun
- Bloom
