Game stuttering + crashing if using framegen

[halcyon frost]

I am running DX12 with all the highest settings (no raytracing) at 1440p with DLSS on quality. My framerate is very high (250-400fps) but I am experiencing micro-stutters and bigger stutters which makes my 1% lows hover around 100-200fps. When it stutters it drops down to roughly 20fps on the 1% lows. Also if I enable DLSS frame gen at all it more or less instantly crashes my game. Is there any resolution to this? I am more concerned about the stuttering than anythng else.

Specs:
MSI SUPRIM 5080 (Base clock)
Ryzen 7 9800X3D (Base clock with default PBO)
32GB DDR5 CL30 6000MHZ RAM (Dual channel)
1000w Platinum PSU
Samsung 990 PRO 2TB M.2
MSI X870 Tomahawk Motherboard

All drivers updated to most recent

Temps are all way below the max (e.g gpu 45c cpu 39c

Do have hardware accelerated GPU scheduling enabled? I believe frame gen requires that and I think the stutters may be because of a to high framerate so try capping it

In old tech land games if the framerate goes above a certain point you get big stutters
