Also getting the massive frame drop to ~1fps + crash to desktop, mostly when trying to teleport. Sometimes it doesn't crash after the frame drop and the fps go back up once I'm in the new area, but most of the time it crashes. This happens every other hour, sometimes twice in a row, sometimes I can teleport back and forth without any problems. Never had this before 2.3.
Gonna try that LOD workaround later.
Windows 7 professional 64bit
Radeon HD6970 (14.4 drivers)
AMD Phenom II X6 1055T
8GB RAM
playing fullscreen windowed, usually with 40-60 fps, maybe 30 in very crowded areas.
(16.08.14) edit:// Turned on LOD Streaming and no crash since two days so far.
(22.08.14) edit:// Still no crash since turning on LOD Streaming. Still, wouldn't call it a solution, just a workaround.
(07.09.14) edit:// Problem seems to have vanished completely, at least for me, as long as I keep on LOD-Streaming. No more warp-related crashes or massive frame drops.
