The GPU is ok, but it needs to be accessed properly.
That was Doom under RISC OS; which isn't doing anything clever with the gpu yet so far as I can tell. RISC OS *does* dynamically compile some of the graphics operations (since about 1989) but that is with ARM code.
Don't know how well the OpenGL stull is supported in RISC OS, in
Not at all as far as I know.
linux it's accessible but AFAIK there is no proper X11 integration so you need to take over the screen (which is the One True Way to do Smalltalk anyway :-) .)
No argument at all with that. I want to go back to Squeak being the only program running so I can use hardware events for the keyboard etc and get better input responsiveness. Instead of guessing when it might be worth taking a look for an OS input event, let an interrupt tell you. Instead of guessing when it would be good to check for another ST process wanting some tie, let a timer interrupt force it every millisecond or whatever.
