View Full Version : Is enabling vsync good for image quaility?

My problem is not speed (performance) but image quality --I am looking for sharp, not blured textures, etc. In that respect, should Verical Sync must be on or off?
Any other parameter or tweak for my quality-minded goal?
THANKS!!!!

V-sync keeps the image from "tearing", so yes, it does improve image quality.

This is a true statement, but since you ask about texture sharpness, v-sync won't do jack for that. In order to adjust texture sharpness, you need to adjust things like level of detail (LOD) and anisotropic filtering. To do this, download and use RivaTuner (http://www.guru3d.com/rivatuner).

I always run my games with v-sync on, no exceptions. On demanding games, this can drastically drop the framerate, but I personally can't stand the "tearing" effect that happens with it off...

I turn it on for some games, off for others. It depends on how much image tearing I get with that particular game.

if your playing games you should just leave vsync on at all times, vsync doesn't affect minimal framerate only maximum framerate. so unless your refreshrate is 60, it wouldn't really matter. i doubt you can tell the difference between 100fps and 150. vsync off is only useful for benchmarks, where you want the higher maximum framerate to higher your average framerate.

There is no real performance increase for having vsync off on any game, there hasn't been for years since all games used a double (or triple) screen buffer. All you do is allow your card to render incomplete frames (e.g. only the top half of it) before displaying the next. 60 half-frames is the same as 30 full frames. This increase you see in benchmarks is purely artificial. And since the sheering makes games look worse you should always have vsync on.

I play Morrowin lately with Vsync on and it is still as fast as if I hadn't enabled Vsync. MW is the most "demanding" game. *cough* B$ MW is demanding *cough*

MW is faster than Aliens Vs Predator 2 on my system for some reason. Using older drivers it's another story though :D
Seriously I have a G3 and MW runs sexy on my system.
