If you're experiencing lag in specific applications or games, but not everywhere, this is almost always caused by the application running in Fullscreen mode. If your game can run in Borderless Window/Borderless Fullscreen Mode, please change the game to run that way in the game's video settings. If you cannot change the game to that mode, you should then turn VSync Off in that specific game. This issue stems from how Fullscreen games render.
If your lag is everywhere (including on the desktop, please read the next section).
INTEL DRIVER ISSUES
After months of testing to figure out what was going on, we finally know the answer. Really bad lag (multiple seconds) and low frame rates (10 FPS) are always due to having the wrong Intel iGPU driver installed on your computer. This frequently occurs due to a Windows upgrade or update without also updating your drivers to the proper version. Windows does not do this automatically unfortunately.
Sometimes, when Windows updates, they change your Intel drivers.
All versions of Windows (7, 8, 8.1 and 10) have driver versions written specifically for the operating system in question. Parsec is a very low level application that requires your graphics driver to be correctly matched to your version of Windows.
Firstly, you must identify what graphics driver your computer is currently using.
- Step 1 - Open Device Manager and find your Intel HD Graphics under display adapters
- Step 2 - Right click Intel HD Graphics and select Properties
- Step 3 - Identify your driver version
If you have an Intel CPU that supports HD Graphics, and it's not appearing in your adapter list, you'll have to turn HD Graphics on in BIOS.
Identifying If Installed Driver Is Correct For Your Version Of Windows
If your driver starts with any other number than the ones listed for each operating system, you are not running drivers provided by Microsoft. You will need to uninstall the driver and use Microsoft’s provided driver via Windows Update.
|Operating System||Windows 10||Windows 8.1||Windows 7|
|Required Driver Numbers||20.xx.xx.xxxx||10.xx.xx.xxx||8.xx.xx.xxx|
How to uninstall your graphics driver completely
- Step 1 - Open Device Manager and find your Intel HD Graphics under Display adapters
- Step 2 - Right click Intel HD Graphics and select Uninstall Device.
- Step 3 - Select Delete the driver software for this device and click Uninstall.
- Step 4 - Reboot if prompted.
- Step 5 - Once your computer is back on and running, Windows should automatically start reinstalling the correct driver for your Intel HD graphics from Windows update.
What happens if my driver never updates to 20.xx.xx.xxx after doing everything above?
If your driver never updates past 9.xx.xx.xxxx or 10.xx.xx.xxxx then Intel never released fully updated drivers for Windows 10 for your Intel HD Graphics.
Even though you may not get a 20.xx.xx.xxxx driver, your updated driver may still work for streaming.
We have had successful low latency streams when using the following drivers under Windows 10
Intel HD 4000/2500: 10.18.10.4425 through 10.18.10.4885
Intel HD 3000: 184.108.40.20659
