Crashes - Pokemon Y - R6025 pure virtual function call

Citra crashes randomly within 10 minutes. This is the only game I’ve played.
I have followed guidance from someone with a similar issue here.
I have just updated my GPU drivers.
I also updated Microsoft Visual C++ recently.
I have Disk Shader Cache turned off, due to another issue I was having previously. I can post a log from a crash with it turned on, in case that matters.
I have no intent to upgrade this device to Windows 10.
FWIW the game typically runs between 85-100% speed but intermittently drops to even 50%.

Here’s some issues I found with your log that might help.

  • You are running out of date drivers for your GPU. You need to install the most recent driver for your graphics card from Intel’s website. Support for Intel® Graphics

I don’t believe I am running an out of date driver.
I have just run the latest available driver from here:

Please follow the instructions listed here: Visual C++ Redistributable Runtimes All-in-One (Jul 2022) Download | TechPowerUp

If this does not work, you will need to update to Windows 10.
Also, as a side note, you should enable Shader JIT again. You will get more performance in game if you enable it again.
