Setting the scaling to gpu on hdmi does create lag.

So much for being exactly the same.

Therefore "tech support" should never ignore the observations a "client" makes, his theory of what happens (evil pixies messing up my ui via X-rays) can be safely ignored.

Glad you found out what happens, I thought scaling in the display could have been the issue earlier, but the graphics card does make more sense especially when it happens during longer games with lots of wrecks, fancy graphics and ASF piling up

well you did hit the nail on the head that the only difference exists in the driver.

I played my wwpc games with hdmi cable. Then switched to display port against nexus for some ladder. Then switched back to hdmi and played some more ladder. The lag difference between these games was not mistakable.

TA4life, I'm really finding this *arduous* to believe.

It is even more difficult to disbelieve for me.
I know people keep saying things like, dvi and hdmi are electrically identical(whatever that means).
However, HDMI comes out of a different port and goes into a different port. The gpu drivers must be treating the different channels at least slightly differently, since hdmi can do rgb, YCbCr formats and you can choose what to set as "content type reported to the display" in the control panel.

Two pieces of copper are electrically the same, but you can stab people with one piece and send UDP packets through another.

Last 16 games: 13 wins, 3 losses. The 3 losses came against nexus using display port. All other games hdmi.

Well Mephi brought back the ui lag, not even hdmi can solve such bs. For me whenever sim stutters, ren also stutters. And even when I assign the two threads to different processor cores they still interact.

better vsync than tearing and id also rather have the slight input lag of triple buffering than stuttering framerate of standard vsync too... if something is at least consistent you can get used to it.

btw hdmi is single link dvi and they are electrically the same, hence converter plugs for dvi<->hdmi are rediculously cheap af, because it just basically reshapes the pins.

keep up with your ui lag research TA. <3 you dont know how deep the rabbit hole goes

I need to turn on vsync for that to work properly and I am not turning that pos on.

pretty sure Voodoo doesn't believe in the powers of hdmi cables.

or anything at all for that matter ._.

HDMI is at 60 Hz.
The display is ASUS VG248 and I have tried running it between 60 and 144 Hz on both dvi-d and display port.
It is butter smooth on 144Hz in windows. However inside FA, there are major problems with stutter.(particularly against laggers)
There is no ui lag early on but as the game progresses it becomes apparent.
This is the problem that HDMI seems to have solved(at least for now).

One thing that hdmi allows, is to set "content type reported to the display"
that other formats do not allow.

This probably is not the cause of the issue.

A problem with HDMI for gamers is that it has limited refresh rates. Old HDMI cables were limited to 60 Hz for 1080p, new HDMI does better allthough HDMI at 4K is limited to 30 Hz.

You could check your refresh rate settings, maybe your computer is set to a 60+ Hz refresh rate that your monitors have trouble with. By using (old) HDMI you would limit that to 60 Hz, matching your HDMI's monitors optimal refresh rate. The DVI-D's could however send the too-high refresh rate to your monitors...

Try using a 60 Hz refresh rate, see if it makes a difference.
