RTGI 0.33 features highly customizable parameters to balance visual fidelity against your frame rate.
: Allows glowing objects like neon signs or lasers to cast actual light onto the environment.
Improved tracking algorithms ensure that light bounces minimize the heavy flickering artifacts typically seen in screen-space ray tracing when looking around rapidly. reshade ray tracing shader rtgi 033 free
FromSoftware games have incredible art but strange ambient lighting. RTGI 0.33 fixes the "grey wash" in dark dungeons, making torches actually illuminate stonework reflectively.
: Blurs the ray-traced noise. A setting of 3 or 4 balances smoothness without rendering lag.
If you are looking for free ray-tracing or lighting enhancement effects, consider these options: : Allows glowing objects like neon signs or
Launch the game and press the key to open the ReShade overlay. Navigate to the Add-ons tab (in ReShade 5.x+).
