Tearing in games and on desktop @ 240Hz

[Anonymous768119]

Hello. I can't get rid of screen tearing and I am not quite sure what this could be due to. It happened more less in the moment, when for the first time I heard coil whining on my GPU. Prior to it everything was silk smooth and sharp.

I have few examples:

Far Cry 5

Looks like DyAc is not helping at all.

PUBG

Before PUBG was astoundingly smooth however many players are complaining that it's not properly optimized. When I ran PUBG after few months and saw that jaggs and texture's tearing I was speechless.

Jagged edges, tearing. Bye bye 240Hz feeling and responsiveness. Especially when I am shooting I feel like somebody is cuffing my arms.

You can clearly see that mouse movement is not constant and quite laggy. Also ghosting got worse comparing to what was before.

My rig:
Monitor: Benq XL2546
CPU: AMD Ryzen 7 3700X No OC
MOBO: MSI B450 Tomahawk
GPU: Asus ROG Strix RTX2060 Gaming OC 6GB
RAM: HyperX Predator 16GB 3333 MHz CL16
PSU: SeaSonic Focus 550W Gold Plus
Mouse: G502 @ 1000Hz
Temps and usage: CPU: ~40C | ~20% and GPU ~40C | ~30% in CS:GO

I tried:
- separating cables from each other,
- removed GPU and inserted again,
- DyAc on/off, Instant mode on/off, AMA on/off
- Fast sync (no any effect however I saw that for some people it's working flawelessly),
- Capping to 239.749 fps with RTSS, it slightly improves smoothness but this is not the way to fix it,
- Ram OC, reducing timings and clocks,
- Capping CPU @ 3.6 GHz,
- Changing power plans,
- Connecting DP cable to different plugs,
- Checked current in outlets (no noises, ground impedance 5 Ohm, stable 230V and 50Hz)
- Reinstalling nVidia drivers with DDU,
- OS format,
- Tried 182Hz tweak (I don't have feeling that it improves anything),
- Updating sound drivers,

I blame GPU but I need your opinions.

PS. I have also inverse ghosting visible on edges, but it's kinda difficult to record it without good camera.
