Bungie another thing. Turning on force_enable_multi_threaded_render_submit fixes the issue but causes bad shadow flicker. Why did you guys think it had something to do with lighting on tangled shore causing the issue? Its a CPU issue. I really hope this message gets to someone. When force_enable_multi_threaded_render_submit is off I get 20-60fps and my CPU does not boost and only 2 cores are used. When force_enable_multi_threaded_render_submit is turned on I get 90-120fps but then I also have horrible shadow flicker but my CPU is boosting correctly and all cores are being used. Proof of Low CPU usage.
