I love that Wildcat demo, considering it was released in 2015 we can only hope that some Wolfenstein port for OCS is in the works out there, with superior frame rate
I think Stunrunner should NOT be in this thread, but some people mentioned it. Lazy port from ST, slow 3d. Terrible
Of course I have another vote for Ambermoon which runs fantastic, texture mapped walls at high framerate even on A500.
