G-SYNC (NVIDIA's VRR) is known to be buggy on windowed mode in Windows.
While the driver only enables G-SYNC for full screen mode by default,
users can toggle it on for windowed mode too, resulting in unstable
refresh rates during Editor usage.
This patch extends Godot's NVIDIA profile to force the default full
screen mode only G-SYNC with Godot.
- Make warnings print only once per session.
- Tweak the message to be less confusing, and mention that the issue
most likely stems from a graphics driver limitation.
When adding an executable to the NVIDIA profile created to disable
threaded optimization, wrong values were passed to `launcher` and
`fileInFolder` params, which resulted in 1) the NVIDIA driver not
applying the profile and 2) the app being repeatedly added to the
profile.
This patch fixes the faulty app creation params and deletes the
potentially corrupted profile if found.
An NVIDIA profile is applied to the current executable to disable
threaded OpenGL optimizations on Windows (see #71472). But because the
application is only added to the profile upon the profile creation,
newer executables won't be added to the profile (e.g. if the profile is
created on first launch of Godot_v4.1-stable_win64.exe, when users
update the editor and launch Godot_v4.2-stable_win64.exe, the profile
will never be applied to this new executable).
This patch fixes that scenario by splitting creating the profile (if it
doesn't exist) and adding the application (if it doesn't have a profile
applied) into two separate steps.
Applications that have been manually added to a different profile aren't
overriden to avoid confusing users who know what they're doing.
