I am getting extremely poor performance with the editor interface after upgrading my computer. I’m running the newest UE4.11 on a fairly fresh windows install. I was previously running UE4 perfectly with my old specs which are dwarfed by my upgraded machine.
When I play the sample rolling BP in editor it works very smoothly but the editor interface is incredibly sluggish. I mean it takes half to a full second for the background of a button to change color when I mouse-over it.
Unreal detected that I was getting less than 10 frames per second when I was in the mesh viewer looking at the sample rolling character. I applied the recommended changes and that didn’t seem to help at all.
Please help!
Edit: I updated my NVidia drivers and disabled G-Sync in hopes that would fix it but it didn’t help. I also updated the attached DXDiag.
Although your report sounds quite dramatic, try the following.
Make sure that your editor doesn’t have any floating panels, lock them all in within the main window. That helps framerate a lot. And try close your blueprints when playing PIE.
This was literally a fresh install of UE4 and I didn’t touch the interface at all so there were floating panels.
I also had no blueprints open during PIE. PIE was actually running very smoothly but not when I chose to play in a new window (PIE). Playing in a new window was giving extremely low fps :(.
Thanks so much for the response! Still looking for more ideas. I just reinstalled Windows completely and am reinstalling UE4 now on my SSD to see if it fixes anything.
I have just re-installed Windows and all my drivers from disc (non-updated). I installed UE4 after all my drivers. This time I installed UE4 on my solid state drive and it is running smoothly (yay!).
I’m nervous to update Windows and my NVidia drivers, though. Is there any known incompatibility with recent NVidia drivers or Windows updates? I may just go ahead and start the updates and see what happens.
So this was solved when I reinstalled Windows and UE4 on my SSD. I have no idea what was causing the issue before but its sorted now. I’d love to be more help to someone else experiencing this issue but the wipe did the trick. All drivers are up-to-date and Windows has all updates installed.
I have had this issue 3 times in the last two years and I am about to do it again. However not a windows install. That never was really the issue for me. It is Something about the engine toolset itself where it gets so bloated it takes an upwards of 30 minutes to load small assets and it isn’t even using half my system resources.
It gets so bad that when I start work in the morning I just end up abandoning because I had to wait so long for a number of things to happen. I loose all interest in dealing with the toolset.
About every 6 months I have to go through and uninstall and reinstall the launcher and engine which is a huge pain. This time around I think I am just going to build one version from source. Seeing as how often the launcher takes more memory to run than the editor half the time…
This issue started around 4.6 and it is just getting worse and worse. My team even discussed upgrading from 4 core to a 8 core (well those of us who haven’t already). But seeing as how it generally uses about 30% of our cpu’s while doing complex calculations and between 10-16 percent of my 24 gigs of ram) we are not confident that the upgrade will help anything… Besides of course shader building and light building which takes about all my CPU and about 60% of my ram…
I will tell you with all the headaches we would have just switched engines if we weren’t so invested in UE so early on.
