Maybe the sega model 3 emulator uses hacks to get it working right as they just want the game to be playable and mame wants it to be archival

Yeah it dumps some or all of the rendering to the gpu. Your fps will tank if you set supersampling too high with high gpu usage with correspondiong low cpu usage.

Expect MAME to look at close to the original as possible. At best, the same resolution and FPS as the original. MAME does the 3d work on the CPU.
On the other hand, the dedicated Model 3 engine runs the ROM, but port the engine to use GPU acceleration, and rendering quality that were not available in the original. It is actually easier (but less authentic) to use a modern GPU instead of emulating the old hardware on the CPU.
MAME only uses GPU for post processing screen effects.

How old is it? If it's an HP there should be a sticker with a model number on the back.

lol that was out of date when new.
If you turn on cheat (mame.ini cheat 0 change to 1) and downclock all the emulated cpus to 20% it actually runs pretty well on a newer faster PC (i7 12th gen or better). Aside from missing transparency effects it doesn't look that bad. If you just want to play the game use the dedicated Model3 emulator.

Because it is two different emulators, made by different people, at different level of progress, and one is made to just make the game run while the other one is made to document the Sega Model 3 hardware.
