Vertical Sync

post #1 of 58
Thread Starter 
What is vertical sync and do I need it always enabled when playing games like diablo 3?

It matches the game's fps to your monitor's refresh rate. I like using it but a lot of people don't.

TLDR:
VSYNC is basically the synchronizing of buffer swaps with your monitor's refresh rate. With VSYNC enabled, frame rates will not exceed the monitor's current refresh rate for that particular resolution. For example, if your monitor is using a refresh rate of 85Hz at 800x600, with VSYNC enabled, you will theoretically never exceed 85fps.

and no you don't need it enabled. I dont play with it on because most the games i play i get over 100 frames and why cap yourself at 60 when you can have 100 frames reliably

This. It helps to stop screen tearing. You'll have to try out the game and see if it bothers you or not. I keep it on for most games.

Vertical Sync is a feature that, when your system is capable of it, locks your FPS to the refresh rate of your display. The typical refresh rate of a display is 60hz or 60FPS, some newer displays are at 120hz or 120 fps.

Do you need to run Vertical Sync? Well it is recommended, as anything over the refresh rate of your display can cause tearing and other anomalies in your picture.

Oh ok but what will happen if games will produce more fps than the monitors' fps?

What if I use a 120Hz monitor?
post #7 of 58
usually when you have vsinc on i a game it wont let you go over 60FPS. ans assuming you have drivers for your 120HZ monitor, the game should match it to your monitor refresh rate

If you enable vsync, your FPS will be locked at your monitors refresh rate. So, in your case, 120 FPS. However, some games lock the vsync framerate at 60 FPS. So, with this being said, you'll only get 120 fps if your computer is capable of pumping out at least 120 fps and if there's no frame rate cap, otherwise the next highest possible value at 120 Hz is 60 fps.

On a 60hz display they can't even be displayed by the display, and that is also why you can get tearing.

No the issue with 120hz displays is that if you run less than 120hz, then it looks weird, so if you go that route you absolutely need to make sure your system can maintain that 120 fps at all times, which is extremely difficult to do in some games.

Ok. So if VSYNC is on with a 60Hz monitor and for example my system, for a certain game, can output 80FPS, what problem will I notice? If I get tearing, won't it be always necessary to just turn on vsync?

For a 120Hz though, I don't know if it's better to enable or disable vysnc. Based on what you guys said, enabling vsync with a 120Hz monitor will lock the frame rate of the game to 120FPS but the actual FPS, let's say, is only 80Hz then what will happen? Disabling the vsync will also produce the same actual FPS. So which is which?
