Didn’t find any discussion about this by googling. But looks like Chaos cloth is totally broken on new Nvidia RTX 50 series cards.
I have chaos cloth on my character. My editor is normally maxing out 120 FPS, but when I play standalone or use PIE, it falls down to 11-12 FPS. When I deleted the chaos cloth from character, PIE is maxing out 120 FPS again. Is this because of the PhysX deprecation from RTX 50 series? If that so, is there any workaround other than using a 2nd GPU? Or maybe it’s going to be fixed on next UE update?
Removing PhysX engine is really a bad decision of Nvidia, they introduced a lot of new tech but this is such a weakness of blackwell series
I’m using:
Unreal Engine 5.5.4
Windows 11 24H2 (All latest updates)
Nvidia game ready driver 572.75
If you already have 40xx, just keep using that without any doubts. If you’re on 30xx, just skip the 50 & see what Nvidia does with next gen. If you’re on any earlier gen & really want to upgrade, just go for 4090 or 4080 super. 50 series is somewhat closer or sometimes worse than 40 series, it just has some gain on AI.
I regret getting my new card when I came to know that they silently removed PhysX from the card. They never say it publicly, maybe it was somewhere in a tiny 2 word notes like conditions apply things.
It was not, hence all the drama. And the melting connectors, and the frivolous performance claims, and the pricing model, and the paper launch… The list goes on. I’m just happy to see AMD managed to capitalise a wee bit on all that. Nvidia’s stance may also create some wiggle room for Intel.
Don’t get me wrong, the transformer and mfgx4 are fantastic technological improvements, dlss vs fsr is not really a competition; those features just do not benefit everybody equally. I’d trade them for more raw raster / compute power.
As outrageous as it may sound, out of the entire Nvidia’s lineup (5060 will not be that great), the 5090 seems to be the most attractive piece.
Have you tried studio drivers by any chance?
There are some rumours floating about regarding March KBs soft bricking PCs. But then again, it has always been the case every update.
