Direct Preview in unity not working - help

[shashkes]

Hi, thanks for your support, i ran the server from cmd and got the log below with the errror that Nvidia drivers might be too old. I updated my nvidia drivers using Nvidia Geforce app to latest driver. version is now 456.71 released 10/7/2020. I restarted the computer and ran the server again but still getting the same error that Nvidia driver may be too old. any idea what is going on?

The server config:.\config\serverSetting.setting is loaded!
The HmdList is loaded! 1 2

@shashkes Which version of the Wave SDK are you using?

Before I did hit this error before, but after I restarted my PC, it will work.

UPDATE: Could you try to use DDU to uninstall the Nvidia and AMD driver and reinstall again?

[shashkes]

Unity 2018.4 LTS + Wave SDK 3.1.94 as recommended here:

ok that was a big adventure,  i used DDU to uninstall the Nvidia (i don't think i have an AMD driver) and then reinstalled but still getting the same error 😞

[VIVE_chengnay]

Could you try disabling your Intel GPU?

The GPU [0] vendor id is 32902, vendor description is Intel(R) UHD Graphics 630

[shashkes]

any instructions on how to do that and how that will affect my computer? 

[VIVE_chengnay]

Which OS are you using? Windows 10?

It will not affect your computer, you can always turn it back on after you finish using Direct Preview.

[shashkes]

yes windows 10

I found this online,

First of all be sure you have 2 Video cards. Example 1 is intel and other one dedicated like nvidia or amd. It is because when you disable one video card then other can automatically takes place of the disable one.

Steps

1. Right click on my computer.
2. Select manage from the options.
3. Now choose DEVICE MANAGER from the left side list.
4. As soon you click on device manager, on your right side your all pc hardware components information will appear.
5. Click on arrow sign of DISPLAY option, you will find both of your cards information.
6. Select and right click on INTEL integrated graphics and select disable.

Note: as soon as you disable intel card, your monitor will go black for 2 sec. don’t panic.

Now your intel card is disabled. Now all your graphics will load from your other dedicated graphics card.

 

NOTE: Please make sure you see 2 video cards under DISPLAY option.
