Trying to double check my settings before doing a stream later tonight and having some really weird behavior that I can’t figure out. Just trying to see if anyone else has seen this and/or has any suggestions. For some reason when I fire up OBS and especially if I start a test stream, GPU usage goes from 70-90% down to like the teens even though MSFS is in focus and so of course in sim FPS tanks. Once it starts it will continue even if streaming/recording is shut off but the software is still open. This is only happening with MSFS but I’m assuming it’s a sim or OBS config issue. I see many people streaming the sim though so I’m not sure what’s up here. As soon as I close OBS my GPU usage will instantly shoot back up to normal (70-90+ depending on what I’m looking at).
After much troubleshooting I think I fixed it. The EGKK add on pushed my vram over the edge and was causing my gpu to choke. Lowered texture resolution from ultra to high and it fixed it finally. Guess an 8GB 2080 Super is not enough for high quality freeware like that and msfs at least at 3440x1440. (Also tried 80% rendering with no success). Time for a 3090 lol.
I have a 2060super @3440x1440 and I am having no issues with airports like that. Seems to me the sim gets hammered by the CPU.I have some of my GPU settings lowered from Ultra to High.Stuff like Clouds,Shadows,Ambient Occlusion reduced.EGGK runs smoothly on my rig. I have yet to try the latest version.If the latest version is that heavy might as well skip.Handcrafted Heathrow runs really well.
On its own the mod was fine. It was once I tried to run obs and stream at it
I am trying to stream msfs with obs but it’s so frustratingly unstable. I have a 3080 and i9 and the machine can’t do it. I am now thinking about streaming using Shadowplay but I want a webcam with a transparent background plus flylive overlay and my voice on my pro mic. Seems impossible unless I record msfs in shadowplay, flylive and webcam in obs. Problem is I get a black background so cannot overlay it on the game footage.
Does anyone know where I’m going wrong? I’m determined not to use OBS because the game is so good. Would love some help if you have a few mins!
What settings are you using for encoding in OBS? Also as I mentioned above I found out I was pushing my texture resolution too high and once I dropped that one notch it helped a lot of things both while streaming and outside of that as well in the sim. Although a 3080 has a couple more GB of VRAM than my 2080 Super.
For me I found using the newer NVENC encoder that’s in the 20xx series and above was doing better in MSFS than x.264 when trying to record local at full resolution for possible youtube uploads later, but both worked fine if I left x.264 at the default veryfast or one step slower preset when streaming, however NVENC looked better as it’s supposed to be a PQ of about x.264 medium which is a pretty big hit to performance even though MSFS isn’t actually using a large percentage of CPU. (typically I’m 35-40% max in heavy areas averaging more around 25-30)
Basically you need to pop out the Stats dock and see where your issue is (render lag, encoding lag, network issues) and go from there on fixing it.
You guys ever find a solution? I can stream just fine using the x264 but I really want to use the NVENC encoder but a weird thing happens.
To make the game not stutter I have to turn off the OBS preview. But when I do that the stream stutters. Now if I put MSFS2020 in window mode and select a different window, either OBS or file explorer, I can play the game just fine, looks fantastic, no stutters, stream looks good with no stutters. I can do this until I click back on MSFS2020 then the stream stutters! I wish I can a find a fix for that because the NVENC stream looks better than the x264.
Sounds like you need to check your OBS settings and also make sure you’re not using all your VRAM. Using NVENC vs X264 shouldn’t cause an issue like that though. NVENC is literally separate hardware from the main GPU and is only used for encoding. It has no effect on the actual GPU performance. However, regardless of x264 or NVENC, the main GPU chip and VRAM are used to a small degree to composite the scene together (sources, overlays, etc) before encoding. Which is why I was getting the tanked usage originally at EGKK with texture resolution on max because I was overloading the VRAM which causes GPU usaged to tank because it has to start swapping to the much slower system RAM.
You need check your “Stats” under View/Stats and see where it says you’re getting dropped/skipped frames. That will help pinpoint where to look for the problem. You might need to just try a different capture method for the sim. (display, game, or window capture) I haven’t streamed MSFS in a couple months actually. It’s possible one of the recent updates changed some things and the sim doesn’t play well with certain capture methods now.
I found my problem! I had plenty of VRAM. OBS wasn’t running as administrator. I had to force it by right clicking it and running as administrator. I still have to turn off preview but I can live with that.
