I’ve recently upgraded from a gtx550ti (~10 y.o.) card to an RX 570 (3 y.o.), and even though I get way more performance, it introduced a noticeable inputlag in csgo.

It just doesnt feel right, and slowmo video capture confirms it.

Have you tried turning off vsync? I'm assuming you don't have a freesync monitor given the jump from nVidia to AMD.

CSGO is CPU bound, I'd suspect maybe it has something to do with the CPU rather than the GPU.

No other components in my setup have changed.

I also experience the lag on my windows desktop while dragging windows.

Did vsync get turned on somehow?

Additionally, the input lag may have been there all along but was not perceivable due to low performance.

No I've done the same slowmo recording test, and it was not there.

Also V-Sync is off now.

AMD even has an "anti lag" feature which apparently does nothing.

Edit: I have a Ryzen CPU, I've expected the full AMD system to work together better.

It's possible your monitor has G-Sync (https://en.wikipedia.org/wiki/Nvidia_G-Sync), and not FreeSync (https://en.wikipedia.org/wiki/FreeSync)

Nah, it's an old benq G2222HDL, without either of those

This might sound weird, but do you have the BenQ DVI driver installed? [1]

Interesting. To be clear, the only change was the GFX card (and driver)?

There is a minimal chance that I might have used the VGA port on my monitor, and now I'm using DVI.

I'm like 80% confident I've used DVI in the previous setup, but there still is a chance that I'm wrong.

I'll probably try getting a dvi->vga converter in the next couple of days and see if this is the culprit.

Can you do a display port cable instead of either of those?

Monitor only has DVI and VGA

Do you only notice the input lag in-games or does it persist when, say, dragging application windows around?
