There are many factors but a 50%-100% better frame rate on the 68060 with hardware Warp3D is likely. Higher resolutions and colors plus special effects are cheaper with Warp3D and more likely as well.

I don't suppose there's a way to get texture filtering on 68k without 3d gfx hardware?
Everything done in hardware can be done in software with enough CPU grunt. The Apollo RTG could add FPGA "hardware" 3D as well.

The SIMD would need to support at least single precision floating point to be able to accelerate much (the Apollo SIMD instructions are integer only as far as I know). A Warp3D driver should be possible but would be a lot of work. SIMD units are not the easiest to program which is why it is good to make them like other SIMD units to use code and compiler support already written. The original plan for the Apollo core was to make it more like the PPC Altivec SIMD unit.

NovaCoder's Quake 2 was written for AGA and has good speed and stability here.

NovaCoder's port is less configurable than some in an attempt to speed it up. I believe Cowcat's port is based on the Hyperion code which has a software renderer as James states above. It has more options and reasonable performance but may have problems on some configurations (testers needed). The thread about it is here on EAB.
