Check performance issues when running additional apps alongside gaming on Windows 11.
Check performance issues when running additional apps alongside gaming on Windows 11.
I recently upgraded my PC and installed Windows 11. For work, gaming, and streaming, I upgraded the hardware. But when streaming, I experience rendering delays in non-game applications. The game runs smoothly, but alerts fail to display properly on the stream. This issue occurs with most high-end titles, though it didn’t affect my Windows 10 setup. I suspect a Windows 11 setting might be the cause. I checked a suggestion to disable hardware-accelerated GPU scheduling, but it didn’t resolve the problem. I haven’t found many other options to adjust. Thanks for your assistance. Your system specs include a 13900k, 3080TI, and 64GB RAM.
This is actually normal behavior - depending on how demanding the game actually is... (having a hard time to believe someone who apparently built their own pc? wouldn't know this) Yes, you can do "multitasking" but its indeed limited by your hardware ultimately.
OP said this was fine in Win10 and only got bad in Win11. While hardware changed also, it's a high end system. I'm watching in case of interesting comments as I came across similar but not identical problems before. In my case it was Win10, FFXIV would have stream lag sometimes, and monitoring stream on same PC always lagged behind. This is an older game that doesn't use a ton of cores, and I have 12 cores so it wasn't running out of CPU. Something else is limiting and I never figured it out. The only workaround I found was that if I stream at 30fps instead of 60fps, the stream problem goes away but the stream monitor lag remains. I can stream other games at 60fps no problem. I also have a vtuber model running on same system, and depending on which order I start the software, I can get weird lag in FFXIV. I'm fairly certain in my case it is a title related problem. When I asked, I was given theories about the GPU encoder overloading but that didn't seem applicable. Maybe it is some kind of GPU choke point? But monitoring didn't reveal anything. I didn't try it then, but now I think more about it, I wonder if increasing the process priority of the streaming software (I used OBS) might help. Otherwise it could be brute forced by using a 2 PC streaming setup. I never tried that since my capture device is HDMI and I have to run DP for my G-sync display.
Still, what I mentioned isn't incorrect either; at some point this is normal and we don't fully understand which applications are affected or if everything remains consistent (except hardware updates and new operating systems). There appears to be a hardware constraint, or possibly a misconfiguration, but Windows isn't particularly good at handling multitasking—so it makes sense to keep programs running lightly while gaming. No? P.S.: Obs is excellent, but occasional lag still happens; I don’t experience this with Shadowplay at all (though it doesn’t record in HDR for some reason, which is a downside since OW is the only game I enjoy with HDR).
I've never faced render lag in other programs before. Yes, you might occasionally notice a slight delay, but not as much as I'm experiencing. The streaming software consistently rendered properly and my alerts remained visible regardless of the game I played. Initially, I thought a game like Last of Us was poorly optimized, but they released patches and I still encountered problems. However, when I tried the RE4 remake, it didn't use my maximum resources and render lag persisted with other programs. If this isn't a widespread problem, it could be related to Windows 11 or my hardware rather than the operating system alone. The YouTube video I found suggested using HAGS with OBS as admin, but it didn't seem to resolve the issue. I wasn't expecting any change in performance since both games ran with identical settings on my new machine compared to the old one.
It was okay before, now it's not. Something has shifted. Simply stating Windows is bad or hardware limits doesn't solve the issue. For one game, I needed to run OBS as admin; otherwise, I only got a black capture screen. No other performance changes have been observed. I'm still curious if boosting OBS's priority in Task Manager could help. I've paused streaming, but I'm considering a return with a new vtuber model in the future. Since I switched to Windows 11, I'll see if any performance differences appear.
You might consider testing Windows 10. At this stage, it’s more about standard troubleshooting. If you’re certain it wasn’t Windows 11, we’d be sure it wasn’t the issue and would keep searching. However, it feels clear to me this is related to the operating system—unless your hardware is faulty, updating to Windows 10 should be straightforward.
