I’m not affiliated with this YouTuber, but I thought this might be useful to someone else. I have a RTX 3080/Ryzen 5800x/32 GB machine and was hovering around 30-40 FPS even after turning a lot of settings down. I think I just haven’t kept up with the best combination of settings. This video got me up to an average of 70-80 FPS (except for in denser areas, where it can drop to 45).
From my understanding from various people online and my own experiences as someone who uses an Intel Card in my main rig (used to dealing with wonky drivers although it’s a lot better these days) Only use DDU if the situation calls for it. Like swapping GPUs. Otherwise just doing a custom install and making sure you check the box for a ‘clean’ install is good enough. Similar adage to “If it ain’t broke, don’t fix it.” Unless you’re getting a lot of crashes or things just seem off performance/visual wise. DDU is probably overkill in most situations.
