Laggy editor

[vincou]

Hello,

I have an issue with my Unreal Engine 5.3.2

My editor is very very laggy, actually unusable whenever i use it full screen.

I tried to modify the RHI → Switched to Dx 11, vulkan instead of Dx12 nothing changed.

I disabled the plugin UDP, nothing changed.

Any ideas?

My PC :

𝘊𝘗𝘜 : 𝘈𝘔𝘋 𝘚𝘰𝘤𝘬𝘦𝘵 𝘈𝘔4 𝘙𝘺𝘻𝘦𝘯 7 5800𝘹

𝘎𝘗𝘜 : 𝘔𝘚𝘐 𝘙𝘢𝘥𝘦𝘰𝘯 𝘙𝘟 6700 𝘟𝘛 12𝘎

Thanks for help !

does it happen too on a fresh project with the basic floor as level map ?

Yes it does.

To be very specific,

It laggs anytime i enter the unreal engine top menu and choose a category.

It works perfectly when i’m using window mode ,

But full screen i cant use top menu, it just freezes like it’s loading something.

Very annoying thing…

I did reset my pc, uninstalled multiple times.

My drivers are updated…

I tried to execute as administrator mode.

hmm this sound like a gpu issue, try to switch to another engine version like 5.2
or if you have another gpu to test it out.

thank you very much for the answers.

I’ve had this issue since 5.0

Try out this one: Intense lag when clicking the menu bar? 5.0.3 - #18 by Low.key.Me

or try to roll back to an old gpu driver

Thank you very much,

I disabled auto hide windows task bar and now its perfectly working !

Actually had this thing since 5.0,

Well done !!!
