Two days ago DLSS4 seemed to stop working. I was surfing and ran across this video by Devil505:
Its kinda long but very informative. He first talks about VR Performance and then goes on about Mods. So you can skip the second half of the video. I went in with a bit of doubt. He kept saying, the results will be so good. Afterwards, I fired up my PC and OH BOY! AMAZING just does not do it justice.
Here is the Readers Digest (Short Story) version of it.
Open Nvidia App/ Updated Nvidia Drivers/ Go to Graphics Tab/ Global Tab(top)/ Disable Shader Cache/ Restart PC.
In C/Users/Your name/App Data/Local/Nvidia/ Make sure you have or Create a folder named GL Cache. (Had the folder. Deleted all files inside. They are shader cache files)
In C/Users/Your name/App Data/Local Low /Nvidia/ Per DriverVersion/DxCache/ Delete the files inside (I had two folders and I deleted them)
In DCS Saved Games folder delete the FXO and Metashaders folders like you do every update.
For Me, I had to reenable DLSS.
Fire up DLSS Swapper and I switched to 3.10.2(Latest Version).
In Nvidia Profile Inspector Pick the DCS.exe, move down to Paragraph 5(Common) and Ensure CUDA Force P2 is on and in DLSS Preset pick preset K.
I could not get the indicator to come on. Maybe it does not come in in VR?
I then fired up DCS. My baseline has always been the (Now dated) Nevada F-5E Free Flight mission. There is a lot of lighting and a huge city so it can stress your system a litte. The Visual Quality was just stunning.
