Steam won't launch on Fedora 42 with Nvidia drivers

We're still investigating this, but in the meantime, setting the environment variable __GL_CONSTANT_FRAME_RATE_HINT=3 should work around it without having to disable the whole driver.

Can someone tranlaste this fix. I saw it posted about above here in this forum, but no one says exactly what to do. What file to edit and add this. What exactly to do. In simple english?
