Hi, when I try to create a new project or enter an existing project, I get this error:
The editor opens, but works horribly badly even with an empty project. Is there anything I can do?
UE4 works perfectly. Thanks for reading 
those three pieces of information are not related.
it shows the graphic card you have in the first line
what driver you have
then the most recent driver at the moment of the engine release regardless of what type of card you have. the driver they have used when testing and building the engine version
that card may not be able to manage UE5. maybe by disabling stuff in the preferences, but is just a lost cause. try putting the engine scalability settings to low
Hey @chuky025 welcome to the forums! I think this is probably nearing the high end for the GT 730 on it’s own, assuming there’s no bottlenecking on the Memory or CPU side there’s not too much you can end up doing to get too much more power out of that card. It is capable of running DX12 but it’s definitely going to hit it’s head with UE5 in many cases, it probably shouldn’t be completely frozen in empty scenes without other factors.
On way to get some frames back would be to go to Project settings → Shadows, and set Shadow Map method to Shadow Maps instead of Virtual Shadow Maps (Beta), this is the old shadow map method UE4 used and is a bit softer.
Disabling Lumen will also net you a bit more FPS
If you can, lower to scalability as Doru recommended and see if that helps. Though I’m no expert on performance so hopefully another user has more tricks available. Let me know if this helps!
OH,I think you should replace your GPU,GT 730 maybe obsolete for UE5.
Thanks to all of you for your answers. I finally managed to optimize it a bit.
