sharedgl VS qemu-3dfx

The repository is located at https://github.com/dmaivel/sharedgl. The project is very much still in an alpha stage, with large portions of several OpenGL versions being missing. However, it can run demoes such as glxgears and minetest with decent performance. This project isn't really an effective replacement for VirGL (except for on Windows) due to its current limitations, however it does provide some 3D acceleration in Linux and Windows guests on QEMU/KVM. It should be noted it does not provide 3D acceleration for the entire VM, but rather passes through the OpenGL calls from one process from the VM to the host for rendering.

There is also https://github.com/kjliew/qemu-3dfx pass-through 3D acceleration for qemu https://www.youtube.com/watch?v=e34mSBxDm7s

I've been porting this to Nixos all week. Handles glide emulation pretty well

As for 3D acceleration, I've seen this repository (no idea if it works) https://github.com/kjliew/qemu-3dfx, and I've also seen that QEMU added the "ati-vga" device, which supports the Rage 128 Pro and Radeon RV100, but those seem to be a bit WIP.

And, here we also have the 3rd option which is less well-known than CrossOver and Parallel Desktop while targeting older Windows games with compatibility issues on modern Windows, QEMU featuring qemu-3dfx for Apple Silicon https://github.com/kjliew/qemu-3dfx

You can check out qemu-3dfx for Apple Silicon macOS. https://github.com/kjliew/qemu-3dfx https://github.com/kjliew/qemu-3dfx/wiki/Apple-Silicon-macOS-Prerequisites

If you are a true gamer from the late 90' s though, you can and probably will run into an old game that doesn't work on modern windows. PCem is really the only good option IMO, but performance is very limited. Especially with glide and 3d acceleration, even the fastest CPUs aren't able to emulate much faster than a pentium II 200mhz at voodoo 2 at full speed (if you are emulating MMX on top of that forget it). Virtualization is possible but not likely to help as win95 virtualization is very basic and doesn't do much gaming things very well. With that said, there are some pretty crazy virtualization projects out there; here is one that requires you to compile everything from source yourself for basically no reason https://github.com/kjliew/qemu-3dfx (have fun).
