"I upgraded from a gtx 1050 ti by a 480 rx." I did not read every word, but I did see it said that DDU should be used and the idea rejected. If you once had an NVIDIA card (in the machine with driver installed, ever) then moved to AMD card, definitely use DDU. I would use it for both NVIDIA and AMD in safe mode, reboot to normal and install latest AMD driver as normal. Reboot after that and test. If for nothing, your system will be better off automatically even if the issue you are looking at is not fixed. If you have any 3rd party overclocking utilities installed, uninstall and install again (all normally) at any time after the above process is done. Look carefully at your bios. Enable or disable HPET and test latency in Windows after. All systems are different (year, make, model, etc...) but on my Intel machine, there is a dramatic positive effect to disabling HPET. Really truly a night and day difference (both measured and felt.) On some machines, the opposite can be true.
