We have multiple different machines at the office, but all of them have either a Titan or GTX 780 OC windforce with I7 3770K’s and 16GB Ram / 7.2K RPM 1TB HDD’s. We noticed in our game and the example demo’s like the effects cave the frame rate is poor (In immersive mode and game builds). I tried completely re-installing the editor, upgraded to 4.1 today.
I disabled near enough everything but the lighting, removing all the post will add around 10 FPS… So we can get 50 fps instead of 40 when everything is switched on in Epic, scaling back to low the effects cave still only runs around 47 fps with post enabled. I then proceeded to benchmark the card I was using, 100 FPS in Unigine Heaven and everything seems fine.
Finally I built the effects cave and measured frame rate still hung around the 45FPS mark.
Anyone have suggestions? (Yes we are on the latest driver versions).
