Hi

I have a pretty decent machine powered with an I7 3770 cpu, GTX 970 G1 from Gigabyte and a 4k G-sync Acer Monitor 1ms ecc.. ecc... and of course a Ubuntu Linux 14.10 OS to drive this rig.

I'm testing the linux implementation of G-sync tecnology with some games and Nvidia Drivers 346.47, for now i have tested:

The Witcher 2:

The game start with no problem, but when i load a save game the screen start flickering and freeze.

Portal 2:

Perfect, no problem at all.

Oil Rush:

Perfect, no problem at all.

Dota 2:

Perfect, no problem at all.

I'll continue testing it and update the post.

Metro 2033 Redux works very well, 60 fps, g-sync, 4k and also Physx.

Awesone.

Tropico 5, 4k, gsync, runs very well, 45-50 fps with all maxed.

Take a screen shot of your Metro bench @ 4k please. All ways wondered what a 970 @ 4k will run like under *nix

I think I may have ordered yours, actually :P Is it this one? I'm really hoping I can do some decent 1080p gaming with my GTX 760 & i7 4770; not too concerned with maxing things out. How's gaming with G-sync and over-60 FPS compared to your previous experiences? :)
Lordpkappa Mar 21, 2015
No, it's this one click.
G-sync capped the maximum frame rate on pair with the maximum hz rate of the monitor.
My monitor is at 60 hz and to go over 60 fps i have to disable g-sync.
The tecnology is awesome, no tearing and the games are really smooth from 35-40 fps.
HadBabits Mar 22, 2015
Ah, I see. So do you prefer G sync over the higher frame rates? Good to hear about the tearing as that's the main reason I use V-sync in most games.
Lordpkappa Mar 22, 2015
In my case i think it's the perfect combination of speed and immage quality, and it's impossible now to have a 4k display with more than 60 hz of refresh rate, the display port interface has not enought band to support 120 or 144 hz.
But believe me, 4k gaming is far more exciting that the 120-144 hz tecnology at 1920x1080 or 2K.
Styromaniac Mar 22, 2015
I've been wondering how 120Hz compares to 4K since you can't have both right now. Maybe I'll focus on 4K for my next setup.
Lordpkappa Mar 22, 2015
4k for sure. I had an Eizo fg2421, an Asus vg248qe an Aoc 24 with g-sync, all 3 with 1920x1080 resolution and 120-144 hz (the aoc with G-sync).
If you tell me, 120hz vs 60hz you'll see some difference, yes, 120-144 are really smooth and movemnts are like butter, but my personal preference is:

1- 4k
2- g-sync
3- 120-144 hz

And the Acer 4k 28 g-sync 1ms is the closer products to my needs.
