When moving my avatar around the game on my 4k monitor (with G-Sync) enabled I and finding my avatar keeps running in the direction I was going without touching any keys on my keyboard.

I am using a PC (Windows 10 Home edition)
i7-7820X
64gb RAM
ASUS ROG PG27AQ 4k monitor
EVGA 1080 Ti
Steel Series M750 keyboard


When I switch the game to run on my 2nd screen (Dell P2414H 1080p) I have no LAG issues.

If I disable v-sync the LAG goes away but I get a lot of screen shearing.


I guess this is similar to the MAC issue .. viewtopic.php?f=7&t=65179 .. but as you have no MAC dev's currently I wanted to put this in a separate ticket to show its a wider issue.

My GPU is running at 100% in full screen mode on my 4k monitor. When I change to window mode the GPU drops to 10%, but the window occasionally blanks in and out rapidly.

Still having the same problem using 0.17.2 ... 4k monitor 100% GPU and LAG, 1080p monitor 10-20% GPU no LAG.

I had assumed that Windows would auto-update my NVIDA drivers, so had not checked how far behind I was.

Now that I have updated (419.17) and have used the NVIDA game optimization tool my GPU usage is down to 15-20% during play time.

Thanks for letting us know.
I personally test with fairly old drivers (398.36 at the moment) but haven't had any issues.
