I havent patched dhewm3 with that code so if hees not done it himself it should be ok

one 560 has less microstutterring but timedemo still crashes with that function

.
cd key check is removed in my build not dhewms and only reason is that someone nicked my key so i cannot play it without
i do have the original cd cases +cd's still so if ID asks ill send them that.
my version has an approximation of carmacks reverse using stencilopseperate not sure if dhewm does.
if in EU using the stencilopseperate version should be safe but theres been some doubt if it also applies in US (patents on algorithms are big sigh).
Productivity is a state of mind.
