Troubleshooting

Got a gray "Server is down" message after start server.

1. Check the requirements

• Geforce GPU supports NVENC
  • Geforce GTX 600 series or newer is required. Some laptop GPU like 940MX is not supported.
• Windows 10 64bits
• SteamVR is installed and the install path is C:\Program Files (x86)\Steam\steamapps\common\SteamVR

2. Try to terminate vrserver.exe, vrcompositor.exe, vrmonitor.exe from Task Manager and retry.

Got "A key component of Steam VR isn't working properly" error

1. Check if the graphic driver is updated

Experience packet loss. (i.e. Got some visual artifacts or broken video frame.)

1. Try the followings.

• Connect with 5GHz 802.11ac Wi-Fi or connect wired LAN to headset
• Lowering video bitrate
• Enlarge video buffer
• Check the router QoS config
  • https://www.reddit.com/r/theNvidiaShield/comments/2rkzgr/shield_portable_gamestream_tips_that_helped_out_a/

IP Address is not displayed on ALVR.exe

1. It maybe a network issue

• Confirm that the headset and PC are connected in the same LAN
• Check the firewall settings (Permit UDP/9944 port)
• If you can use adb, run adb shell ping -c 5 (IP Address of PC) then check success of ping
• Use a tool like iperf to test your local wireless bandwidth, especially UDP.
