Some software has been found to conflict with SteamVR or SteamVR driver installations. If you have any of the following software installed, try uninstalling it and re-testing:

• Razer Synapse
• Asus AI Suite
• Avast antivirus
• JDS Labs ODAC USB Audio device
• Older Apple Cinema displays with devices attached through USB
• TP-LINK 300Mbps Wireless N PCI Express Adapter TL-WN881ND

• Update GPU drivers from Device Manager (Device Manager > Display adapters > Update Driver Software)
• Unplug any USB devices that aren't being used
• Disable power management in SteamVR (SteamVR > Settings > Developer > Disable Power Management)
• Disable Windows Defender
• Disable wifi adapter in Device Manager (Device Manager > Network adapters)
• Set your PC to 'High performance' (Windows key > Type: power > Power Options > High performance)
• Set NVIDIA power management to Prefer maximum performance
• Reset CPU/GPU overclocking to default

1. Quit SteamVR and go to the Steam Client
2. Find SteamVR under Library > Tools
3. Right-click on SteamVR and select Properties
4. Click on the Local Files tab
5. Click Verify Integrity of Tool Cache

If this doesn't work, try deleting the local files. Follow steps 1-3 from above and select "Delete Local Tool Content." Double-click 'SteamVR' in the tools library to reinstall.

1. Unplug all Link Box cables from your PC
2. From your host computer, go to SteamVR > Settings > Developer. Make sure the Developer Settings checkbox is checked
3. Click on Remove all SteamVR USB Devices. Make sure the Link Box's USB cable is not plugged in and click Yes
4. Once this is complete, quit SteamVR, plug your Link Box in (USB, HDMI, Power), and re-launch SteamVR

Open your Frame Timing graph (SteamVR > Settings > Performance > "Display Frame Timing"), then launch a process-heavy VR game and look for frame timing spikes.

If you see spikes, the issue is probably related to CPU performance.

High CPU temperatures can create performance problems. There are several programs available that can help you control CPU temperature management. Remove dust build-up on your PC case and fans to ensure adequate air flow.

Power cycle your PC and press the DEL key on boot to access your motherboard's BIOS.

Make sure that any safe modes that affect performance are disabled and other power restrictions are lifted.

The process for accessing the BIOS differs between computers. For further details, look up the process for your particular computer or motherboard.
