Frame limiter change has no effect

[XXXBold]

PCSX2 version:
PCSX2 1.5.0-0 - compiled on May 2 2019 (Linux Version, from PPA) on Linux Mint 19.1, 64-bit (see below for more infos)

PCSX2 options:

• Preset: Balanced, Multithreaded VU enabled
• Apect Ratio/Aspect Ratio Overwrite: Widescreen 16:9
• Wait for Vsync is disabled

Plugins used:
GS:

Description of the issue:
If I enable/disable the frame limiter, the Emulator always stays at 100% of its speed.
I've tested this in a menu, where the Usage is pretty low, so it should go up to probably 400% when the frame limiter is disabled.

I've tried this with 2 different games, both are affected (I guess the game doesn't matter for this issue).

On the same machine, but on Windows, the frame limiter does work as expected.

How to reproduce the issue:
For me, it's 100% reproducible:

• 1. Start any game, e.g. open a menu where Resource usage is low.
• 2. Enable/Disable the Frame limiter with the hotkey, see no difference in runspeed (always ~100%).

Last known version to work:
Unknown, stable seems to have the same issue

Try running the emulator as admin.

[XXXBold]

Well, there's no "admin" on Linux, but I've just tested as root.
The problem persists.

[pixelherodev]

Now that you mention it, I've had the same problem.

Works fine on Windows, but compiled from source under Devuan the frame limiter does nothing.

Is turbo mode working ?

[KrossX]

Maybe the compositor is forcing vsync? Try a PAL game and see if it locks at 60 fps as well.

[XXXBold]

You mean the frame skipping I guess? Just enabled it (Turbo with TAB), and yes, this works.

[avih]

Does it work when you disable framelimit via the config dialog? (config -> GS) Do you have vsync enabled?

[XXXBold]

Maybe the compositor is forcing vsync? Try a PAL game and see if it locks at 60 fps as well.

I have an EU BIOS, sorry :/

Edit: My games are PAL (EU), but the're locked at 50FPS.

Does it work when you disable framelimit via the config dialog? (config -> GS) Do you have vsync enabled?

Doesn't make a difference if enable in the Dialog or toggle with F4, Wait for Vsync is disabled

Try this

[XXXBold]

Try this

Ahh, that solves it, cool, thanks!

I need to start PCSX2 with vblank_mode=0 /usr/games/PCSX2-linux.sh

However, not sure if I should close this issue (Probably PCSX2 should handle this itself?)

[mirh]

Indeed. There must be some problem between pcsx2 and mesa driver.

[XXXBold]

I'm not sure if that's a proper solution, but if I add the line "export vblank_mode=0" at the beginning of the file /usr/games/PCSX2-linux.sh (Which is created by default anyway if you install pcsx2-unstable), the Frame limiter is working if you start it over this script, without need to set it up in the terminal manually.

However, the entry from the startmenu (which is created by default, aswell) is not starting using this script (Why is it created then?), it's launching the command "env GDK_BACKEND=x11 __GL_THREADED_OPTIMIZATIONS=1 mesa_glthread=true MESA_NO_ERROR=1 PCSX2".

IMHO it would make sense to add all these Parameters to the .sh script and just launch "/usr/games/PCSX2-linux.sh" in the start menu, or what do you think?

[mirh]

That "externally" forcing the driver is no solution.

[BlackLotus]

Which GPU and which driver?
I have the same problem since I updated my system a week ago with my RX 570 since I upgraded to mesa 19.1.1
Didn't yet check if a mesa downgrade solves the problem, but llvmpipe (LIBGL_ALWAYS_SOFTWARE) didn't have the problematic.
Will eventually check later on what the exact source of the problem is.

[XXXBold]

GPU: R9 290X
Driver: most recent 19.2-git mesa from oibaf ppa: https://launchpad.net/~oibaf/+archive/ubuntu/graphics-drivers

I don't really want to perform a downgrade if not necessary, might break my system xD

🤔
Are you sure compositor, DE, or whatever might not have some kind of override in place?
"Vsync always on, but if I force it, it works off" doesn't seem a bug floating around.

[XXXBold]

Hm, I don't really know if it's affected in general, in Half Life 1 (OpenGL aswell), I can enable/disable VSYNC ingame, and it works (50->100FPS).

The first issue you refer to doesn't apply for me, because for me setting vblank_mode=0 DOES have an effect, as mentioned above.

The VSYNC value for me is 50 FPS/Hz, because I have connected a TV on HDMI (As a mirrored screen to my main monitor), which is its max. refresh rate, and VSYNC can't vary between these 2 (Guess that's a driver issue/limitation, but that's another story).

For your 2nd link, the suggested command in a response ("LIBGL_DEBUG=verbose vblank_mode=0 glxgears -info") prints out this for me:

[mirh]

Hm, I don't really know if it's affected in general, in Half Life 1 (OpenGL aswell), I can enable/disable VSYNC ingame, and it works (50->100FPS).

NVM, then we are broken.

[F0bes]

Is this problem solved on the latest master?

[XXXBold]

@F0bes
I've just tested it with latest master, self-built for Ubuntu 20.04 (as described in the wiki).
This time, it worked as intended (FPS could exceed monitor refresh rate when limiter was disabled). However, I'm currently running on a NVIDIA GPU, so I'm not sure if the original problem is solved, because I'm using the proprietary driver.

[F0bes]

Thanks for testing. This issue is quite old and no one has reported this issue for some time so I'll close this.
In the case that this is an issue It'll just be reopened.

[manioo8]

For any poor soul that ends up here from a google search after having problems with the pcsx2 frame limiter not reaching above 60fps no matter the setting on steam deck, there's a built in option for limiting frames to 60 that also affects pcsx2. Before diving into more debugging, make sure to press the quick menu button while the game is running (the three dots button . . . ) and change the cap from 60 fps to off. Sorry that I'm re-opening this issue, but if that helps somebody in the future then it was worth it as this is one of the first results for this issue on the steam deck.
