Hey Chief! Recently I've watched a FR33THY's video about display scaling. He advocates that we should use display scaling if we have a monitor compatible with it, claiming that it brings a lot less of input lag. You still think that GPU scaling should be used? I have a GTX 1080TI and don't intend to use ULMB, just 240 with uncapped FPS in CS:GO (only game I play).
Depends.
It's not universal advice. This was usually mostly true in the old days, but with faster GPUs, there are cases where GPU scaling outperforms display scaling. So with one computer, you have less lag via display scaling, but with another computer+display, you've got less lag via GPU scaling.
Pseudocode:
IF (GPU = fast & recent) AND (Display = has slightly laggy scaler) THEN use GPU scaling.
However, you'd probably need an LDAT or other similar tool to confirm which is better for your setup.
In your case, you've got an incompatibility consideration (ULMB mode incompatible with monitor scaling) and so you have no choice but to use GPU scaling on some models of displays when using G-SYNC or ULMB.
So that's the two answers.
(A) The "depends" factor where you might have less/more lag via GPU scaling or display scaling.
(B) The "compatibility" factor that prevents monitor scaling (e.g. a specific mode).
