My unreal editor (blueprint graphs) is choking a little, and I feel as if the refresh rate (hz) is low at certain times, it’s a little laggy. This happened after I changed my GPU, from a 1050ti to an RTX 4070. I already updated the driver to the newest version in a clean driver installation, I even formatted the computer, checked the refresh rate of my monitor, but nothing helped.
I can’t tell why is this happening, but here are some ideas:
- Have you tried to disable
Hardware-accelerated GPU schedulinginGraphics Settingsin Windows? I remember I had some issues with this being enabled in past. - Clean
IntermediateandSavedfolders from project (please make backup before messing around this). - Put GPU in maximum performance mode and see if it makes difference, maybe power manager is too aggressive on new GPU.
I already tried that, but it didn’t work
Greetings @kuekua
You mentioned that it felt like the FPS is low at certain points. If it’s happening during scenes or in a map I’d start with turning on the FPS monitor in Unreal Engine and see how much it’s dropping. Did you make any additional changes? (I’d usually recommend setting your NVidia Control Panel 3D settings back to global default. But, if you completely reformatted and reinstalled the control panel all together then there’s probably no need)
Does this occur on one specific project or plugin? Or is it regardless of project? Thanks!
@FrostyJas I notice small stutters mainly when I’m hovering the mouse over an element in the editor, such as buttons, functions in the event graph, variables. Any movement of the mouse over these elements causes a certain “choking”.
Do you have any sort of freesync/gsync enabled? I’ve experienced issues with this setting enabled before with Unreal. If so, try turning it off to see if it makes a difference.
I have G-Sync active on my monitor, and in the nvidia App it says “use the 3D application setting”
Worked perfectly! Now how do I deactivate it only for Unreal?
You can follow this video here, but I’ll reiterate in case it gets removed in the future for whatever reason.
You essentially just add Unreal Engine 4/5 (whichever you’re using) to your list of programs, and change the “Monitor Technology” from “Use global setting (GSync compatible)” to “Fixed refresh”
This is a relatively weird issue I’ve seen before that’s also fixed itself on a few occasions, so it can go away on its own sometimes to.
