nope. 14fps on pentium 200mhz with 32mb ram in 512x400 or similar mode (640x480 was too much)
"My game froze for 100ms on a one time shader compilation dropping... totally unplayable!"
I get it, shader compilation is a little pain point but it isn't that bad. Some compilation times are less than the frame times we used to play at in the 80's/90's.
Still remember the concern when Quake 3 would require a GPU as they were not entirely ubiquitous then. It was the right more and it helped the industry forward but it was a little pain point at that time.
Quake 2 and Half life had pure software renderer for people who didn't have 3D acceleration cards such as Voodoo.
It was slow but worked on ANY graphical card :)
