I have created a new UE scene with minimum stuff loaded and no raytracing.

When I start grooming after adding editGuides the comb function is working but very slow. And I have a beefy machine with a RTX 3090. So I added the Filter option. But when I start using the comb function the hair dissapears when clicking. And then after a long time it appears with the modifies groom.

Performance on youtube look way better. So any idea's whats goin on here?

Cheers,

Marcus
