Optimizing Input Latency / Nvidia Driver settings

[DC9V]

Hello! 
I'm coming from an e-sports background, where minimalizing input lag is important in order to minimize the chance of random input delays due to the possible misbalance between the physics engine and the framerate. That being said, I'm used to play video games at 240 FPS or more, with a physical monitor latency of 5ms or less, while making use of Adaptive Sync technologies like G-sync. V-sync in comparison is very bad as it nearly doubles the frametime, whereas Adaptive Sync only adds 1 or 2ms of latency. Now I'd also like to reduce the latency when using a Wacom tablet in Affinity Designer. I've experienced a bit by using a software called HIDUSBF, in order to overclock the polling rate of my Wacom tablet. Although I understand that Wacom tablets work differently than mice or game pads, I feel like it still does improves the responsiveness and the detail of a quickly drawn line.

My questions and thoughts are as follows:

1) Is Affinity Designer going through dwm.exe, in other words, is V-sync always active?

2) Does Affinity Designer have a fixed physics tick rate for pipelining input?

2) What happens if I enable G-sync for windowed mode in the GPU driver settings?

3) When I create a custom profile for Affinity Designer in the "Manage 3D settings" section of the driver, will it actually have any impact?

 

Cheers!

Our apps use DWM as it's always active in Windows, Disabling G-Sync should result in a smoother presentation. For your other queries they shouldn't have an impact on our apps. Is this something you've customized for any other apps similar to ours and what processes/methods did you use?
