Hardware: 670 4gb and i5 2500k, both not overclocked. Settings: 4x AA and 16x AF (forced, high quality) High shadows Perf. AO (via inspector) RCRN and Skyrealism concurrently, no SSAO. Made sure these weren't the problem, first thing. Actually, I think it was you, techangel85, that suggested these. Very cool. The rest generally follows the recommended settings/ini edits, enb's included. No optimized textures on this installation. VRAM fluctuates around 65–70% of max (average ~2800mb of 4096mb) when testing (running around Whiterun, outside, interiors, etc... for 8–20 minutes until crashing). I would normally blame my processor for performance before my GPU, yet my GPU load is all over the place (anywhere from 12–99). Also, the problem persists through updating my drivers. I doubt this is a mod issue; but I'm baffled. Any thoughts? Thanks
