The Window mode is using slightly misleading naming. "Fullscreen" is actually "Borderless" and "Exclusive Fullscreen" is the real "Fullscreen," in addition to that there's also "Windowed"
V-Sync can be disabled completely, there is no hidden FPS cap
NVIDIA Reflex and Radeon Anti Lag 2 are supported
The Frame Generation menu supports DLSS 3 Frame Generation and FSR 3 Frame Generation. There is no official support yet for DLSS 4 multi-frame generation, but that can be enabled via the NVIDIA App override mechanism
Upscale Method has the following options "Off," "IGTI," "DLSS," "FSR," and "XeSS." This option gets disabled when you enable DLSS Ray Reconstruction, because for that to function DLSS must be activated
Upscale Quality has the usual "Performance," "Quality" etc. options for upscaling. Ultra Performance is included, too
When FSR is enabled, the "Upscale Sharpness" settings lets you adjust the additional sharpening applied by FSR. With the other upscalers this option is disabled
Dynamic resolution scaling lets you set a FPS target that the upscaler will try to achieve with various quality settings
When "Upscaling" is set to "Off," you can pick the following Anti-Aliasing methods: "Off," "SMAA," "TAA," "DLAA," "FSR" and "XeSS"
The "Graphics" menu the following presets: "Very Low," "Low," "Medium," "High," and "Very High." Please do note that "Very High" does not maximize all settings, but the differences are minimal
There's a good range of options for textures, light and shadow and geometry
The Camera Effects section lets you disable annoying things like motion blur, depth of field, bloom and vignette. You can also adjust the Field of View—I found the default setting quite alright (usually I increase FOV)
In the Ray Tracing section you get the following profiles "Off," "High," "Very High" and "Ultimate"
When you have an NVIDIA RTX card, as soon as you enable any ray tracing technique, the "DLSS Ray Reconstruction" option becomes available. When enabled it will take information from DLSS upscaling and bring that into the RT effects increasing their quality
Ray tracing object range lets you select how close world objects have to be before they are considered for ray tracing
