I know someone who had issues with stutters in the game and it turned out to be his recording software. If you are running some kind of recording software, then maybe try turning it off and see if it makes a difference. Just a wild, wild guess
The game is poorly optimized, coded, everything. Everytime we get close to a big update the game is literally starts deteriorating. Every day I have more stutters, more bugs and things not working as intended . It happens everytime a big patch is about to hit.
I have no desync issues and I play on a AMD setup with a 4090 and DDR5 ram and run on w11.
Make sure your bios is updated, make sure you have resizable bar turned on as well. Ensure your motherboard nvme slot is not contested with the GPU as well. Some lower end motherboards do not have enough PCIe lanes, and some nvme slots go through the southbridge and are not connected directly to the CPU.
Also dont follow those guides, go back and reset your settings. Desync is not a problem with graphics, itโs a problem with latency, packet loss, and where the server decides if itโs a hit or not.
Make sure your NIC is running at 1000/full duplex and not something like 100/half-duplex
