EDIT: Nvidia updated Portal RTX to include their own presets. These likely aren't necessary anymore. I made some custom presets for Portal RTX because it doesn't have anything lower than High. There's 3: Medium Medium-low Low Low doubled my FPS compared to high while retaining good visual quality. The main drawback with Low is that reflections are disabled. Medium and Medium-Low are almost indistinguishable from the higher presets to me, so I'd stick with those if you want more performance while retaining great quality. To use this, drag the file (rtx.conf) of the desire preset into the Portal RTX installation folder and overwrite the existing file. I have this set to DLSS off by default, but feel free to turn it on.

What is this? This updated release removes all dependency on the mtndew.dll file - fixing the RTX crashes, while allowing players to be fully updated to 0.6.1.0 How to Install Ensure that the ElDewrito Mod is fully updated to 0.6.1. If the player has used the previous version of this fix they must also download the original mtndew.dll file - which is also attached here. Go to the Game's Directory and replace the current binkw32.dll - and mtndew.dll if the player has used the previous version - with this one.
