and what resolution do you guys prefer?
Disadvantage 4:3 stretch gives you is :
4:3 black bar
Even a player with a 4:3 screen SHOULD use 16:9, more FOV = more info, simply
Unless you have graphic card shittier than GTX 970, use 1920x1080, you'll not loose/win significant FPS
I played before on 750ti and i5 4460 my fps was same on high/low settings
Now I have 1070ti i5 9600KF, same shit FPS is the same.
Only noticable difference is how unsmooth game feels on HIGH settings compared to low.
Example go in config edit resolutionscale and ur still gonna have same FPS as before
