So I have a kinda crappy computer, but this game was actually playable to me, still, not enough fps for a FirstPersonShooter game where you need precision and etc. So i decided to lower the resolution to help my performance, so I changed it from 1360x768 (my main resolution) to 1024x768 (the lower you can get in this game) but it had no effect at all, I was clearly still playing in my main resolution (though in the settings it was showing "1024x768"), I thought maybe I needed to restart the game and so I did, but still, no changes. This (plus the fact that everytime I get "stuck" on the ground and can't walk or shoot for a few seconds) makes the game unplayable to me.
So, plz help.
As far I know, it does work but it changes the native resolution too. If it doesn't work, you should try to change the native resolution on your system. If it's a known bug, you can also report it in the bug sheet that the CMs have provided
