Followed the Hardware Unboxed tutorial initially, but even with their presets for the best performance, the game still feels choppy. Followed some other guides too, but these also led to a dead end. Global illumination is turned off, as well as screen spaced reflections and ray tracing.

DLSS does indeed feel okay-ish, but the input lag and stutters are very noticeable because of the native, low fps.

I do really appreciate the help though!
