TFTCentral reported input lag increase and no variation in response time, but Prad, after the firmware update, reported no input lag increase and variation in response time.

Just wondering if the firmware update is the cause of both differences or if either Prad or TFTC made errors during testing.

Which firmware update was this?
You know, the one way back in 2015, right after TFTC discovered the freesync+overdrive bug.

Ah yes i remember that, i looked at prads measurements and they're definitely different, but i think prad only tested it at 60hz based on the translation. Would be interesting to see tft redo the response tests on an updated model.

EDIT: Nvm saw prad do 144hz as well, yeah its different.

Sorry I didn't see your question sooner. Answer is No. I did some reading and older GeForce cards (GTX 600 series) cannot drive 144hz. It maxes out at 120hz. Some people think it is related to "pixel clock timing."

I'm anxiously awaiting Vega, but in the interim, I think I'm going to pickup a cheapie Radeon 470 just to test and ensure my 144hz range actually works without issue on my Nov 2015 build unit. I also need something to tide me over until next year (when Vega supply and prices are normalized). biggrin.gif

Question 1: For games that hop between the Freesync to Non-Freesync ranges, is the change noticeable?

Question 2: When did Asus update the firmware? I have a unit with a Nov 2015 build date and am hoping they fixed the Freesync input lag on my unit.

Use v-sync with freeSync. That way if you go above the upper limit you will be capped at the monitor's refresh rate.
post #165 of 290
According to this Reddit thread (https://www.reddit.com/r/Amd/comments/42yfjv/freesync_and_frame_limit/?sort=confidence), adding vsync introduces input lag. A better approach is to use a frame rate limiter tool to cap fps instead.

All that said, is it noticeable when hopping in and out of the Freesyne range at the upper end? I ask because I'm trying to determine if I should keep the default 35-90hz range or do the mod to 54-144hz). Mind you, I don't yet own an AMD card so I can't test it for myself.
post #166 of 290
Yes, it is noticeable when you get outside the range and the smoothness. Frame limiters don't work very well, at least for me. When I use it, even @85 fps, it still goes out of freeSync range. My guess is that there is a frame or 2 that escape frame-limiters and it is annoying to me. I find v-sync to be the best way, and no, I don't notice increase in input lag even if there is some.

If I game at half resolution (1280 x 720) where 4 pixels become 1, does the monitor display crisp graphics, or is there some smoothing/interpolation?

Interpolation pictures for 720p are in this page of Prad's review:

http://www.prad.de/new/monitore/test/2015/test-asus-mg279q-teil7.html#Interpolation

(1st native, 2nd 1080p, 3rd 720p)

Basically, looks like utter crap.

Dude, you are my savior. We have a similar setup but I only have one MG279Q and no VR but the same fanatec wheel. I've been wondering how the Fury X performs in asserto Corsa compared to my R9 290. I want 144fps + on 20+ man servers. My R9 290 is around 60-80fps with my current setting which is all eye candy to max except for medium shadow res, normal smoke generation and low reflection settings. Thx chap!

Here's a screenshot of my Assetto Corsa Benchmark results with triple 1440P (7680x1440P) Refresh set at 144hz.  Although i'm not hitting a consistent 144hz, the game is still fairly smooth.

 

 

FPS:

AVG =102

MIN = 31

MAX = 129

 

With two FURY X's.  I'd imagine a single FURY X and MQ279Q at 1440P 144hz will be no problem at all.  :thumbsups
