Since last week , out of nowhere, I started to have problems on Ue4. For example, when you try to connect 2 nodes on event graph, there is a stutter on engine. It’s not easy to work around on Ue4 like this. Sometimes, when you right click open the dropdown menu, it instantly disappears OR when I switch to chrome while Ue4 is in the background, screen refreshes like a milisecond black screen.
I have Ryzen 5900x and GTX2080 Super. I don’t have any problems while playing any game or any other program. I was using this perfectly until this week. I don’t know why. I saw some posts and tried disabling nvidia overlay and udp transport message setting in Ue4. Those didn’t work either.
I opened task manager on my second monitor and there is notrhing wrong with usages either. I switched only one monitor to see if the problem is coming from 2 monitors, didn’t work.
I upgraded my project to 4.26, it’s the same on that too.
Unfortunately I think it will be a try and fail situation. Thankfully graphics card drivers don’t take too long to update/downgrade (and we now know what the problem was). I will be passing on the Nvidia’s 461 drivers for now. Worth trying again with 462 when that releases.
