[BUG]: [Linux] PCSX2 Qt: NTSC framerate stays at 59,00 hz

[LvDown]

Describe the Bug

NTSC framerate stays at 59,00 hz; no change in the settings, restoring to defaults or setting to 59,94 on the ini files work. Because of this, all NTSC games have stutter, making them annoying to play. May be caused by a rounding error? The ini files list the default as 59,939999. PAL games are not affected.

Reproduction Steps

Fresh install of PCSX2 Qt version through any means (flatpak, appimage...). Does not happen on any WxWidgets version, or Windows. Unknown if happens on macOS.

Expected Behavior

The default framerate should be listed at 59,94, and the games should then run smoothly.

PCSX2 Revision

v1.7.3327 (appimage)

Operating System

Linux (64bit) - Specify Distro Below

If Linux - Specify Distro

Linux Mint 21; based on Ubuntu 22.04

This smells like locale issues, since the comma....

What does export | grep LANG give you?

[LvDown]

declare -x GDM_LANG="en_GB" declare -x LANG="en_GB.UTF-8" declare -x LANGUAGE="en_GB" This is the output of the command. On a side note, thanks for responding so quickly!

@DCMVM can you restore defaults for me

[LvDown]

@Mrlinkwii If you mean pcsx2 defaults, the issue still persists, and if you mean locale, I don't really know if that is even possible, but I'm somewhat new to linux, so I wouldn't know, and google isn't much help

[stenzek]

Does running PCSX2 with LC_ALL=en_US.UTF-8 /path/to/appimage change anything?

[LvDown]

Yep, that was it, it's a locale issue, restoring defaults now works and it reads the ini file properly

[stenzek]

Okay. We'll leave this open then, I'm redoing the conversion routines to use non-locale-specific functions... it's just proving a little painful, since std::{from,to}_chars doesn't support float types in older versions of the standard library on Linux, including the 20.04 version :(

[LvDown]

Well, then thank you for your help and good luck with the project, it's amazing!

[stenzek]

Try https://github.com/PCSX2/pcsx2/pull/7083, hopefully should sort it out.

[LvDown]

The ini is now generated with 59.94 and qt seems to read it just fine, and modifications done in settings are properly reflected in the ini file, everything now works perfectly, no other issues (so far) to be seen! I'm a bit new to github, should I close the issue?

[Mrlinkwii]

@DCMVM leave it open and when the pr is merged the issue will be closed

[stenzek]

Great, thanks for checking!
