i upgraded from R9 280X to Sapphire Radeon RX 580 Nitro+ (since my R9 280X died) and I have noticed a huge input lag in all games...
I reinstalled my Windows 7 (clean install), I also tested Windows 10, different drivers using DDU (both Crimson and Adrenalin).
I also disabled HDCP, so software doesn't seem to be the issue. Everything is basically set up the same as it was with R9 280X... I even tried the same driver that I used with 280X.
280X was very responsive, there was no input delay whatsoever...
It's much harder to aim in games, thanks to the input lag. Yes the input lag is also present in the desktop.
Yes, V-sync is disabled.
Is it common for GPUs to have more input lag than others?
Is RX 580 known to have this input lag?
Maybe my older hardware doesn't go well with my GPU?
ASUS P8P67 LE
8GB RAM (2x4GB) DDR3 1333MHZ.
Intel core i5-2500 (non K)
PSU Corsair AX750
I tested 2 different monitors I used with 280X, both via DVI and HDMI.
I also noticed some horrible micro stuttering that wasn't present with R9 280X... It comes in and go away every few seconds (it doesn't matter if i play demanding games or less demanding games like Left 4 Dead)... Only Vsync fixes it, but Vsync gives even more input lag...
And sometimes rarely I get FPS spike, again this was never happening with 280X.
