Extremely slow performance on a very high end pc, confused

Hey there unreal team. So in the default viewscreen all runs well, but inside bp editor and in animation and mesh screens I get ~10 second delays, mouse mis-reads, and sometimes assets can’t even be moved or repositioned, requiring a restart of unreal.

My hardware is

32gb ram

dual titan x

i7 8 core processor

~1tb SSd

Unreal doesnt play nice with SLI; if you have that on?

I play on a similar (but slightly worse rig) and don’t have many issues.

I didn’t have sli on. It’s super odd, my rig should handle the editor okay but its nearly not usable. Sometimes I really can;t use it and have to shut the engine down.

Honestly I have no idea; I have a 5960X, 64gb ram and a pair of 290X’s (well 290s flashed) and the thing runs fine.

Try a diff gpu driver?

Titan X, 32gb ram, 3.7 quad core

Running the kite demo I get like 10fps. What the ■■■■ is going on here
