Tried this mod which is said to be tested on doomsday engine, but honestely telling it's not really working, I got 14FPS which is unacceptable and lot's of error messages.
My machine is
core i7 3.8ghz
radeon r9 fury
So I don't think it's really my PC as ordinaly levels and ports runs as excepted.
Perhaps this is the new benchmark for you guys to test your new builds.
Come on guys we need this mod working really, that would be dream come true.
(with a better quality to connect the levels with new areas also)
