PG248Q... gsync don't works?

Talk about NVIDIA G-SYNC, a variable refresh rate (VRR) technology. G-SYNC eliminates stutters, tearing, and reduces input lag. List of G-SYNC Monitors.

PG248Q... gsync don't works?

Post by Zazie » 09 Nov 2016, 14:37

I tried g-sync with emulators. Mame 106 is seen tearing, Kega full screen goes' crash (error StackHash_0a9e). What can I do?

There is a g-sync test? It may be broken?

It's hard to tell what's really going on since I've never tried those programs with G-Sync.

Are you using display port connector on your monitor?

Are your Nvidia drivers updated?

Is G-Sync on in the drivers and running your apps in exclusive fullscreen?

Do you have any Source or GoldSrc games that you can test? just type fps_max 60 in console and G-Sync should kick in. Nvidia also has a g-sync pendulum demo http://www.nvidia.com/coolstuff/demos#!/g-sync

A simple google search shows both of those emulators have known issues with G-Sync functionality. Just search "Mame 106 G-sync" and "Kega G-Sync" and you may find some existing material on another site or forum.

I don't use either emulator, so I can't give further input.

I found that gsync doesn't work with direct draw, which is why it didn't work. :(

Does this mean gsync simply doesn't work with Source games? :(

It defiantly works with source games.

Source games isn't DirectX... It's Direct3D or OpenGL depending on platform.

GSYNC works with both Direct3D and OpenGL

But the problem is emulators don't always work with GSYNC. Some of them do, but not all. Emulators often use DirectX, but they can be modified and adapted to be compatible with GSYNC. I've seen MAME successfully work in GSYNC mode to support arcade games that run at odd refresh rates (e.g. 54Hz). But it requires quite the fiddling with command line options, and works best with VSYNC ON powered GSYNC. Fortunately the emulator itself is a framerate cap unto itself, so you don't get the VSYNC ON input lag that occurs at hitting maximum GSYNC framerate...

For G-Sync to work in MAME you can use the OpenGL renderer, available since MAME 0159. The Direct3D renderer should also work.

Direct Draw will NOT work with g-sync.

This could be added to the Gsync 101 guide. What do you think, jorimt?
