An error occurred initializing video core

Yuzu Support
#1

Hello! I had my cousin (who recomended Yuzu to me) download and set it up for me a few days ago since I wanted to play Smash Ultimate. The day of the instalation (it was on wednesday) I could play a couple of matches no problem. Today I tried to open Smash and got the error mentioned above. I have a copy of the text from the Yuzu log which I’ll paste bellow.

My relevant PC Specs are:

-Ryzen 5 1600 at stock speeds.
-Sapphire RX 5500 XT with the latest drivers Radeon Experience has.
-12GB Crucial Ballistix 2400MHz DDR4 RAM.
-Running on WIndows 10 (up to date with all updates and patches)

If any aditional info from my PC is needed please tell me.

Here is the text I copied from the log.txt:

In order for us to provide better support, we need to see the log generated by Citra. This guide will walk you through how you can obtain the log file: How to Upload the Log File.

#3

Your GPU drivers are too old to use yuzu. You need to install the latest optional ones.

#4

I wanted to open Radeon Software to check that I effectively had the latest Drivers and for some reason it showed as if i didnt have it, which is strange. I’ll try re downloading the Adrenaline Software and Drivers again and get back to you. Thanks!

#5

You need 21.3.1. Should be out as an update option in Radeon Software now, but manually installing it also works.

#6

Yeah, now it works!

For some bizzare reason, Radeon Software dissappeared from my PC, which is really strange since I remember updating drivers and stuff last week.

Thanks for the help!
