But this way the video encoder gets frames by the graphic card. Otherwise it wouldnt everytime when the renderer idles. And this already happens when you stop moving the mouse on a static background or loading screens etc. Not very nice if you want to capture video.
But I see what you mean. So the game still runs for real with 50 to 70fps swapping. and still gets to 25fps if I put a shitload of holes into the wall with my pitchfork while standing directly before it.
but thats ok. I can test real performance then without the forceupdate and if its ok for me I can switch it on to be able to record it flawlessly.
So big thanks for your fix.
