Have you tried [url=https://bitsum.com/parkcontrol/]unparking your CPU cores[/url]? I run the game on an Intel 9700K with an Nvidia RTX 5080 (upgraded recently from RTX 3070) and a 3440x1440 175Hz oled gaming monitor. I'm obviously CPU limited formally but Destiny 2 runs super smooth with high graphics settings, V-Sync + G-sync on in nVidia control panel, V-synd off in-game, max fps in-game set at 172 Hz and Nvidia Reflex set to ON + Boost in-game to minimize latency. The framerate cap is probably not necessary when running G-sync + V-sync together, though. The Reflex Boost setting only added around 5-10W of increased power consumption measured with the Nvidia app. I've made sure [b]all CPU cores are unparked[/b] (never parked for power saving reasons) for several years with good results. I still let them downclock when not active, just not park themselves. Framerates are high and latency low and most importantly I have absolutely no stutter anymore. I've run Windowed Fullscreen (which now identifies as Fullscreen) since Bungie implemented DXGI Flip for Destiny 1/27/2022 and consider this the single biggest QoL improvement in Destiny 2 ever, since it made alt-tabbing to desktop (DIM) instantaneous. I firmly do not believe the switch to Windowed Fullscreen is the underlying cause for stutter issues. Another possible cause of stutter mentioned on youtube is that the WiFi module of never motherboards can cause repeat Windows system errors that could manifest as stutter. The most recent Nvidia driver 591.44 fixes the performance issues that came with Windows 11 25H2 update recently. It didn't mention Destiny 2 specifically but I do believe it increased my fps in the Renegades environments by around 10%. Can't say if it reduces stutter since I don't have stutter in the first place.
