If this is a proprietary case (such as those from Dell, HP, etc), which it looks like this is, then it probably doesn’t.

My suggestion is to get even a bargain bin $50 case and switch to that quickly. Far less limiting and probably has cable management components all over.

Dead by Daylight switched to UE5 and immediately had noticably bad performance.

Silent Hill 2 Remake is made in UE5 and also has bad performance stuttering. Though Bloober is famously bad at optimization so its possible it might be just Bloober being Bloober.

STALKER 2 is showing some questionable performance issues for even high end PCs, and that is also made in UE5.

Now, just because the common denominator for all these examples is UE5 doesn’t mean that UE5 is the cause, but it is certainly quite the coincidence that the common denominator is the same in all these examples.
