# RunAsGPU
2+
RunAsGPU is a tool designed to give users a nice way of controlling applications
3+
on what GPU an application runs on. I decided to write this tool to overcome the
4+
issue with the use of `DRI_PRIME`, which for some users may or may not include
5+
certain issues. This tool also helps users that aren't too technical with CLI,
6+
having a proper simple-to-use GUI. GUI should be simple to use with an App
7+
Selection screen (yes, you add apps manually, sorry not sorry), you select the
8+
app, and you run it. Simple GUI in mind, really.
9+
10+
## Use cases
11+
Documentation coming up soon. This project will actually appear sooner than my
12+
other projects, like for example, take
13+
[OsintgramCXX](https://github.com/BC100Dev/OsintgramCXX) that actually takes
14+
forever to finish.
