Generally keep in mind your computer's power saving options.If the host has a G-Sync monitor, try to disable G-Sync and check if the encode latency improves.You can find older drivers in NVIDIA's Advanced Driver Search page Consider trying an older driver version like 472.12 if your version is newer. Some NVIDIA users on Windows have reported issues with the newer drivers, causing unusually higher encoder latency, latency spikes and significant capture issues.They can easily worsen the experience if not carefully configured If the host happens to have experimented around with advanced settings in Settings > Host > Edit the configuration file, remove them and restart Parsec. Some Vulkan games' windowed borderless mode still act just like fullscreen, so make sure to try the actual windowed mode In case of high encode latency, you may see a difference from tweaking between fullscreen and windowed, or windowed borderless.If all guests support H.265 and have it turned on, you may see better performance than with it off If the host has an AMD card, AMD is usually known for having worse encode than NVIDIA and even Intel.At the moment you will be able to connect to streams with the slower software decode, using FFmpeg 4 (libavcodec58) Hardware decoding is currently unavailable, but the intention is to bring it back eventually. Linux: Parsec is undergoing a transition from libva to FFmpeg.In that case you'll want to lower the resolution and FPS on the host to compensate for it There's a setting in the overlay itself and Parsec's settings to change the decoder to something else, but if the guest's hardware is too old, they might be unable to use a hardware decoder at all. If the guest's overlay says Software H.264 next to the latencies, Parsec isn't using the hardware decoder which results in much worse decoder latency.The web client does not have access to low-level hardware optimizations or hardware decoding, if you're having issues with the web app, you should download the native app for your system If the guest is joining via the browser, you may notice Decode says N/A.However, you should also keep in mind the following things: In general, lowering the resolution and FPS of the host will reduce the latency. What to do if the decode or encode latencies are too high? When streaming 60fps, you don't want to go above 15ms. High numbers can mean major issues to the stream. Decode is the guest device, and encode is the host device. Put a very visually active game or video on the host, then press Ctrl+Shift+M on the guest to see the information below.ĭecode and Encode is the time the device takes to handle a single frame. Check the "Checking overlay latencies" part of this guide to learn more about how to resolve this Yellow hardware warning (The host's resolution or FPS is too high for your hardware to keep up): This will show up whenever Parsec sees that the client computer's latency (the "decode" latency) is way too high, where it is not able to keep up with the stream in time.If it does not, refer to the other tips given by this guide in the "Checking network reliability" part further below It is possible that simply lowering the bandwidth limit in the host computer's Parsec settings, or switching to 5ghz Wi-Fi or ethernet resolves the issue. Yellow network warning (You are having network performance issues): This will show up whenever Parsec notices significant packet loss and network congestion.To resolve this, check our separate guide about the software encoding warning Red encoding warning (The host is using software encoding): This will pop up whenever the host computer cannot start the stream with a fast hardware encoder, and Parsec had to use a lower performance software encoder.The person that is connected to a computer is able to see warnings when Parsec detects that the stream is not acting well. This article goes over checking Parsec's latency info and console log for information on why the stream is performing poorly, and some tips to fix it depending on what Parsec shows. The quality and performance of a Parsec stream is very dependent on the network and hardware of the host and the people joining the stream.
