FREESYNC ULTIMATE ENGINE

[Klemen]

If i set normal freesync engine i get smooth 144hz, while if i set ultimate engine i get only 120Hz... On monitor's software it shows either way 144Hz

I am using Premium High Speed HDMI 2.0 HEC cable that came with samsung's monitor, gpu supports 2.0b (1070)

 

does it mean cable is too weak to utilize 144Hz on 1440p resolution on ultimate engine? because, well, i mean like, it does get 144hz on a standart engine, but on the ultimate engine (enhanced version) it only gets as far as 120Hz 

 

so does it mean I should get a better cable of HDMI or just proceed with display port right? I dont have any display port on my hands atm, but i just dont know if the cable is the bottleneck here... 

 

1440p

Ultimate engine with hdmi gets me only 120Hz

standart engine or 1.0 engine gets to a 144Hz with HDMI2.0 

 

Games are capped at 120Hz but nontheless monitor says it is still 144hz, which would really just lead me to guess that the cable is the obstacle here

well, over HDMI you cant enable G-sync to actually use the freesync compatibility. You will still need to connect your GPU up via DP to actually use G-sync compatible Freesync.

hmm so does that sums up to conclusion that the version of HDMI is too weak for that purpose or r you trying to say HDMI overall isnt g-sync compatible w freesync  ?

Gsync does not work over HDMI, it will only work with DP. Also, many times the cables that come with monitors are bottom of the barrel trash and are 99% of the time cause of issues with screen glitches with new systems or monitors.

It does now but only with G Sync compatible displays (so basically anything that's Freesync). They had to do this to support Big Screen displays as those only really ship with HDMI ports on them. Normal G Sync & G Sync Ultimate both still require DP to function.

So if i had amd's card then i wouldnt need DP? since you said only g-sync requires DP to function fully

Well yes (I run Freesync Ultimate on my 5700XT via HDMI with no issues) but it SHOULD also work fine on your 1070. Check the Nvidia Control Panel to see if the G Sync section is available and that you can enable it. It also might be called HDMI VRR.

So with that you mean you run at least 144Hz with no problem in games?  

 

because you know, monitors dont understand I am using another's brand GPU and maybe cable really isn't the problem here, since then It'd be displayed on the monitor's interface that I am cut down to let's say 120Hz, but it still recognizes 144Hz, which yea maybe it might really be a GPU thing then, which would mean and explain that Nvidia's gpus dont really like HDMI connectivity over freesync displays

 

Fascinating, truly fascinating i must say

Yeah, 1440p 144hz or 2160p 60hz with Freesync Ultimate Engine selected in the monitor settings and that is reflected in the AMD driver suite too.

 

Its actually entirely possible Nvidia restrict G Sync Compatible displays to 120hz in software but I can't say that as a fact, its just a guess.

 

Edit - Yeah I was incorrect, GSC supports displays up to 240hz....
