masterian: is the "force restart" option on in the display options?
darthspudius: Good call, stupid feature I didn't even notice was there. Thanks boss. :)
Not a stupid feature because it helps load games faster in current level and between levels once present is loaded, decrease lag and performance problems (not related to HID but the way engine is made with multiple archives and layers, also related to lighting and shadows which never was properly optimized) so you can set higher features. Also remove a lot graphical glitches, prevent save game corruption and broken scripts (very possible if you quick save/load often or your game freeze/crash). Basically the longer game is running, the more performance degrade and harder to calculate complex geometry by engine so renderer restart between maps is to solve that to some point.
