Need some advice on how to find out what's wrong with my GPU RTX 4070 Ti Super or how to prove that it's broken

Hey everyone!
The main problem is screen flickering.
Please, take a look at the video below.

I had to use my smartphone to record it, because when I try to make a record of my screen using different software they actually do not show the problem.

I am currently working on a project in UE5 and at some point I noticed that this flickering happens in about ± 5 minutes after I turn on Ray Traced reflections and Ray Tracing Translucency. Sometimes it takes more time or less to start flickering.

But the most interesting thing about this flickering is that I also started noticing it in Battlefied 1 game - the only game I ever played on this PC.
As far as I now there are no specfic settings for Ray Tracing features in this game and I actually use the default graphic settings. I guess, this game does not support Ray Tracing at all.

My PC:
CPU - 13th Gen Intel(R) Core™ i7-13700K 3.40 GHz
RAM - 64,0
GPU - NVIDIA GeForce RTX 4070 Ti Super - Palit.
OS - Windows 11.

The computer was assembled 5 months ago and all the components have a valid warranty.
The seller said that before sending the PC to their office I can try to carry out different tests at home in order to be 100% sure that the problem really exists.
I ran the following:

  • Free tests:
    1. FurMark (older version).
    2. Superposition Benchmark.
  • Paid 3dMark tests:
    1. Speed Way - Ray tracing benchmark for high-end gaming PCs.
    2. Port Royal - Ray tracing benchmark for graphics cards.
    3. DirectX Raytracing feature test.
    4. Steel Nomad - Cross-platform, non-raytraced benchmark for high-
      end gaming PCs.

By the way, during these paid tests my PC works even quieter than when I use Ray tracing features inside UE5.

It’s very strange, but during all of the mentioned above tests the flickering wasn’t noticed by me.

Steps taken:

  • Changed DP cable
  • Changed DP ports
  • Installed diferrent versions of gpu drivers (including older versions).

I haven’t tried reinstalling Windows 11 OS, because I am not sure whether it’s a good option or not.

Any advice on the current issue would be much appreciated!

even the taskbar is flickering so this may be a display issue not unreal or the gpu. dunno howto switch that in windows 11 but you could try using the intel gpu on the cpu to test display integrity.

Thank you for the replies.
I’ll try to describe possible changes tomorrow.
