Nvidia image sharpening on or off?

General Discussion
1

Anyone using it?

Does it increase input lag?

I have a 2560 1440 rog gsync, I tried it, thought it looked better, but not sure if it was psychological.

and what is the gpu scaling option? I think it’s to make stuff fit the screen properly, but seems to make no difference on or off on mine.

I’m leaning towards turning it all off again now…

I think it maybe beneficial on old games but not overwatch…

Thoughts?

GPU scaling is used to determine how to handle games with non-native aspect ratios and/or lower resolutions. If you run a 4:3 game on your 16:9 monitor, should there be black bars on the sides or should the image be stretched to fill the screen? That kind of stuff.

Then there is also an “integer scaling” option which can be used to scale up old games (mainly 2D games) without getting a loss of image sharpness.

Edit: I don’t think GPU scaling will have any effect, positive or negative, if you have it on when playing a game at native resolution and aspect ratio (2560x1440, in your case). So there shouldn’t be a need to turn it off.

Regarding image sharpening, I don’t actually have an nVidia card so I can’t say what kind of performance impact their algorithm may have on both FPS and input lag. I can say, though, that I use Radeon Image Sharpening on my AMD card and it makes Overwatch look much more crisp with virtually 0 impact on frames or lag.
(Of course, RIS is a different tech than nVidia’s variant, so YMMV.)

Or turn it on? (tick the box)

I try and work on the less processing the better.

Thanks for the info.

I think I read somewhere that ow is only 16:9. They didn’t want players with nicer monitors gaining an advantage.

Test image sharpening on your pc. Ctrl+Shift+N in practice range and look at the sim number. if it stays under 10ms with image sharpening on and you like how it looks, use it.

7.1 sim value 20 char with or without.

Ehh, run it then if you like the looks.

Yeh think I will, again I dunno if it was just I was playing bad last night, but in my head the game felt “spongey” hard to explain. Maybe the net was having an off night.

I would not trust that number.

  • My normal settings: SIM is 5-6 ms, everything is super smooth.
  • Normal settings + v-sync: SIM is 16, so much lag it’s near unplayable (for me). Seems like SIM can be trusted here.
  • Normal settings + windowed mode: SIM is still 5-6 ms, but there is noticeable input lag. Not as bad as with v-sync, but enough to make aiming feel awkward.

So yeah, some things will increase input lag without changing the SIM value. Also, it seems like SIM is heavily tied to the frame rate, or maybe even entirely derived from just frames?

I suggest you play for a while (a week or so) with sharpening on, and then turn it off again. If it does increase input lag you should feel it immediately.
