Warthog_Farmer Posted July 25, 2016 Posted July 25, 2016 Hi guys... Quick question. I've noticed that the performance in my Rift has been getting slowly worse and worse - although I am becoming more used to flying about in lower FPS situations so the nausea isn't as bad.. Before I start playing with graphics settings and trying to tweak I thought I'd ask this quick question: I ShadowPlay most of my multiplayer with friends just incase we have funny moments. I ShadowPlay the "Desktop" and run a black image in fullscreen and then the Rift image is displayed in the middle. This is the best solution I've found to prevent the imaging being recorded in a weird, skewed, ratio... Anyway - GeForce Experience FPS counter is recorded in the top right of the DCS window. On playback I have noticed the FPS occasionally locks to 30 and will remain there for a few minutes. Other times I have noticed locking to 45 and, again, staying there for a while. I'm not too up to speed on how everything works but I am wondering if there is a V-Sync setting, or G-Sync setting or something that is interfering with DCS/Rift. It just seems unusual that the FPS isn't jumping around, as usual, instead it is solidly locked at 30 or 45 (The two figures I have noticed so far) I hope this makes sense.. I'm sometimes a bit crap at explaining things. Any help/advice is always appreciated :)
Warthog_Farmer Posted July 25, 2016 Author Posted July 25, 2016 Had a quick session of VA server there. Average FPS 45 with an occasional spike to high 80s - looks almost rhythmic (like a heart monitor) as if it's trying 90 out and doesn't like it so goes back to 45. 90% of the time it's at 45FPS pretty consistently.... CPU usage peaked at 55% with average mid 40%'s. RAM usage 11GB (16 avail) GPU temp fairly consistent 65-75 degrees with fan speed 40% as per EVGA Precision X curve. GPU Memory Clock 1253 solid GPU Memory Usage 100% constantly (6GB) So it's my understanding the GPU usage should be 100% as much as possible. Is there are thermal issue at 75 degrees that's causing the card to lock to 45FPS? I'd have thought the clock speed would have reduced if it was throttling. The temp target is set to 83 degrees in Precision X. Cheers :)
uri_ba Posted July 25, 2016 Posted July 25, 2016 Try freeing up some GPU memory by lowering texture quality and lowering AA. To See if that helps. If you constantly need to load and unload textures it might be the spikes.
