To give you a little background information (some of which may seem basic to you):
Your GPU is providing the frames that are pushed to your monitor. This is what allows you to ‘‘see’’ things. It also calculates the graphical parts of most programs (games, videos, ect.).
Your CPU does the main legwork of computer calculations, and whilst it’s good at a lot of things, it’s pretty bad at computing stuff like graphics and and the like. Hence why a GPU is needed.
Your specific CPU model, the
Intel(R) Core(TM) i3-8100 CPU @ 3.60GHz, also has access to a so called iGPU, which is short for Integrated GPU (meaning it is a GPU that is packed together or inside the CPU)
This used to be just for people without a dedicated GPU to still be able to get a picture on the monitor to use. Nowadays, they’ve gotten pretty good. To the point that these CPU + iGPU chips have better GPU performance than older dedicated GPUs like the one you’re currently using.
Not really too odd, considering:
Your CPU (Intel(R) Core™ i3-8100 CPU @ 3.60GHz): Released in 2017
Your GPU (NVIDIA GT 210): Released in 2009
Performance has come a long way since then.
As for how to remove the dedicated GPU, that goes a bit beyond Citra Support. What you can do without actually removing the dedicated GPU is manually tell programs to run on your iGPU instead:
Shut down your computer and take a look at the back of your computer. It should look something like this:
Your display (monitor) is currently connected to your dedicated GPU’s display connector, which means your PC will use your dedicated GPU for it’s graphical processing.
You should connect your monitor to your motherboard’s display connectors. That way, it will use your CPU’s, in this case, superior integrated GPU for your PC’s graphical processing.
Turn your PC on again after connecting your display to your motherboard. If it doesn’t show you an image, then your integrated GPU is likely disabled in your motherboard’s bios → which would mean you’d have to look up a tutorial on how to turn it on for your specific motherboard.
If it boots right away → great.
You should upload a Citra log file after using Citra for a bit on your iGPU so I can see what GPU driver version is installed for it. I would be able to provide you with the right drivers and instructions to update it to the latest version available for some extra performance.
Ofcourse, this is all optional. If you’d rather wish to have someone more tech savvy with you when doing something like this, or you just don’t want to go through the hassle, that’s completely fine. It’s up to you.
