dwaldrop Posted Sunday at 07:54 PM Posted Sunday at 07:54 PM I have had an issue with DCS VR for a while now and have finally gotten tired enough of it to try and figure it out. I am running a Pimax Crystal Light with an NVIDIA 4090RTX on an Intel 149000kf. Almost everything is DCS VR looks awesome: cockpit is crystal clear, terrain and clouds look almost real life, other aircraft (when I hit F2 to look at them) are amazingly sharp, ground vehicles and ships are perfect, smoke, rain, waves, etc are almost real life. The problem is when I am fighting another aircraft, whether it is AI or another player, the aircraft looks shimmery. Sometimes streaks come off of the trailing edges and looks like the plane is melting or in warp drive. Other times I see what I figure is called ghosting, like I see a ghost image of the entire wing as the plane maneuvers. When I click to the F2 vies of the same plane, it looks prefect. I have spent a lot of time fiddling with all of the settings and have just about gotten the shimmering and ghosting removed but it is still noticeable. Sometimes it is worse than other times but there seems to be no pattern as to why it gets worse and then gets better, never going away completely. I understand that DCS VR is very resource intensive even for a 4090 but one would think that it could do better, especially given that all of the other visuals look so good. Any help or ideas would be appreciated greatly. My specs are listed below. Thanks!

sleighzy Posted Monday at 04:51 AM Posted Monday at 04:51 AM If you haven’t already then add the below lines to your C:\Users\username\Saved Games\DCS\Config\autoexec.cfg file, create it if it doesn’t exist. DLSS_Preset = 'K' HUD_MFD_after_DLSS = true This will use the latest DLSS preset, which will reduce some of the ghosting. DCS currently uses C by default even though it’s on one of the latest DLSS versions. The second line will mean that DLSS is not applied to the MFDs / HUD so you don’t get the ghosting there that DLSS can introduce. Try with DLAA as well. 2 1 AMD 7800x3D, 4080Super, 64Gb DDR5 RAM, 4Tb NVMe M.2, Quest 2
