Yeah, increasing LOD to 400 just kills my CPU. No noticeable effect on my GPU.
Basically, they cut the LOD hardcore for SU5 to scale it down for Xbox. Now they’ve given it back to us as “beyond ultra”. I tried setting LOD to 400. Gives me about 15 fps. That’s what I used to get prior to SU5 with my LOD at 200. I can’t use LOD above 200. It just murders my system.
