Question consistent high frametimes (30-50ms) in Fullscreen

[justintoe22]

Specs GTX 1080. Ryzen 2700X. 16GB RAM. Win10 on Samsung 970 Evo Plus SSD. non-gsync 1080p 60Hz monitor shooting for ~16ms @ 60fps.

Really not sure why. Games in fullscreen have a Render Latency / Frametimes of 30ms-50ms @ 60fps. Even uncapped fps up to 140+ has a render latency of 20ms in fullscreen. Borderless window and Windowed are fine at 16ms @ 60fps.

I first noticed this issue about 2 months ago, which was 2 months after I did a clean install on the 970 Evo I had just bought at the time. Every game, DX9, DX11, DX12 has this issue now. Here's what I've done so far with no solution:

• clean install nvidia drivers
• set gpu to enable msi (message signaled interrupts) mode
• system restart
• Enable / Disable fullscreen optimizations & run as administrator
• Force V-Sync on & off through nvidia ctrl panel (when fps is above 60, high render latency persists E.G. 20+ms @ 140fps)
• Changed scaling mode to GPU / Display
• Cleaned registry errors
• Changed graphics settings & resolution
• Turned on nVidia low latency mode to On / Ultra / off
• Ensured power plan is High Performance
• Ensured nVidia Prefer Maximum Power
• Disconnect Peripherals & Bluetooth
• Ensured RTSS & Afterburner does not run / start
• Cleaned game cache & Verify Integrity
• Disable in-game overlay for Steam Origin and nVidia

Welcome to the forums, newcomer!
When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for the motherboard?

I did a clean install
Where did you source the installer for the OS?
