Question 1060 3GB slowing down at 1440p?

[u700]

I noticed something strange.

When I play Shadow Warrior 2 at 1080p high detail I get over 90 fps, GPU usage is above 97% at all times.

I now have 1440p monitor and when I switch to 1440p high detail, the GPU sometimes slows down to 50 - 60% usage, and framerate drops to 40 or below because the card is not working at full speed.

The usage drops, but the clock speed stays the same. VRAM usage is about 2.7GB, so I'm not hitting the VRAM limit.

The card usually slows down for about 30 seconds at random times. This never happens at 1080p.

What could be causing this behaviour?

full system spec? include make and model of the PSU
what the cpu/gpu usage and temp during the game?

What CPU?

full system spec? include make and model of the PSU
what the cpu/gpu usage and temp during the game?

CPU: Ryzen 5 1600 (stock)
Mobo: MSI - B350M MORTAR Micro ATX
RAM: 8GB ADATA - XPG Z1 (2 x 4 GB) DDR4-2800
GPU: Gigabyte - GeForce GTX 1060 3GB 3 GB Windforce OC
PSU: Cooler Master - MasterWatt 550 W 80+ Bronze Certified Semi-Modular ATX Power Supply
Storage (system): DREVO D1 M.2 2280 240GB SSD
Storage (games): Toshiba - P300 2 TB 3.5" 7200RPM HDD

When the game is running:
CPU usage: around 30%
CPU temp: 60°C
GPU temp: 72°C
RAM usage: 5.9 GB
VRAM usage: 2.5 GB

This seems to be happening only in some games but not others.

2.7 GB is very close to your VRAM limit.

As a fellow 1060 3gb user, I have never seen my vram at 100%, but rather 95% at 2.8gb, I get frame drops at that point, so I've assumed that there is something like reserved vram or driver shenanigans going around and that anything close to 2.5gb is effectively capping vram and dropping frames.

I noticed this only happens with Freesync on. If I switch it off, the GPU stays at 98 - 99% usage at all times.

I checked in the game "the forest" as well. Everything works fine, but if I switch Freesync on the GPU keeps dipping to 80.
