I'm thinking the studders are from building a shader cache. In the nividia settings, there's "shader cache size" option. I have that set to 10 gb. The wierd shadow thing is caused by SSS+DLSS as others have said. Why someone would want to use DLSS with a 4090 is beyond me. I assume it's for testing purposes only.
If you get staters you need to disable all power efficient cores in the bios. ED didn't optimize this, so they don't work well in the MT version. Give it a like so that as many people as possible can see it and find it helpful.
1/ on the 40xx series above 4060 - we don't need DLSS. period. ^) Maybe DLAA - on. 2/ Shadow glitches - turn OFF DLSS. And SSS - ON (its cool feature makes shadows from all ground objects from Directional light - ie Sun) 3/ Stutters - check your CPU load or check your SSD health. Game needs to load some assets and cpu and ssd need to work with it. good video btw. like
That's screen space shadows. Anything that occludes a part of the screen that is important for calculating the shadow will cause visual glitches just like screen space reflections.
That's just how screen space effects work. It's using what's available in the z buffer on the screen to cast rays. But anything in the way might cast a shadow it shouldn't.
Great video mate - wondering why you are using DLSS with DLAA at Balanced with a 4090? no....................... you absolutely don't need to. DLAA yes. DLSS no. Not for you nipper. Cheers pal.
It seems that the fog is pretty bugged. It's better to have rain only, with no fog at all. I was playing on a multiplayer server with the Overcast and Rain 3 preset, and it was amazing. The heavy rain effect can be as dense as the thickest fog. Furthermore the horizon is not visible with the rain only.
Try making shadows flat and non flat etc. BTW: I have that same weird "nodge" every while and then in graphics, though more often. Annoying it gets only in Syria map. Think many with faster computers havent really noticed that so much. Though my nvidia is 3 gen. older :D But yeah I saw a video where was about those shadows, where was said it seems to be just a bug for now, because the grass"level" kicks in and new shows dont apply correclty while nearing new surface (it makes secondary shadows to grass etc bushes, but loses the ones earlier sawn from upper. If you want totally get rid of that just tunr secondary shadows off. But something could be done by making shadows flat only (or vice versa, dont remember for sure). Still it leaves some bugs. But yeah I am more nervous about that bumb in graphics (kinda freezes for a "second") (very shor second :D in your video) Have you tried outside views? Are they running / changing without any lag for you? (in maps where those little fps stutters are. I dont have s-atlantic map, but my kangoroo fps map is Syria.) caucasus and marianas run smoothly. And syria is only at ground level and that only when view / camera is somehow changing (so in outside view, pretty much all the time). I had same probs back in spring 2023 in syria map, but they were gone for good whole summer. Now with 2.9 path they came back, though fps, when its not bumbing in fps it runs +30% fps with my old as fart computer :o And that A lot. BTW have you tried to launch MT-DCS? The separate exe file in /dcsmainfolder/mt-bin/dcs.exe (=multithread version) instead of normal "shortcut´s" /dcsmainfolder/bin/dcs.exe (=ST)
The performance this update seems to be improved as far as stutters. Syria is now playable for me, although stutters do still somewhat persist. DLSS and FSR are great, but i've had great performance at medium/high settings since MT update. Problem is the damn stutters since almost 2 months now. The thing is they happen even if the averages are well above 100fps. I know other players are still having serious stutter problems, FSR and DLSS wont fix that do to the nature of these stutters always being 1 fps / game freezes. Edit: i can also now open DCS and then headtracking software and it fucking works!!! Really annoying when it takes 10 minutes to join a server only to realize you didn't open your headtracking app and now have to restart DCS for it to work.
It's been like that for a while now (and yes, it was a great fix when they did it). You can disable automatically scanning devices (may have some impact on smoothness) and force it to rescan for new hardware in the controls menu manually, if needed - the options are on the top of the controls menu tab if I remember correctly. A very worthwhile change.
Read what Shrike has said - you don't need to reload DCS, you goto adjust the controls and enable hotplug, rescan, then turn it off again once trackIR has been "hooked in" with DCS again. This way it's not constantly scanning for new hardware, but you avoid having to reload from scratch
