GUI: Bring "SPU GETLLAR Busy Waiting Percentage" to UI

[TigiHof]

Quick summary

"F.E.A.R. 2 - Project Origin" has severe screen flickering and constant crashes!

Details

Release rpcs3-v0.0.32-16614 seems to have introduced the described problems, if only subtly. Subsequent releases since then seem to have made the problems worse, so that "F.E.A.R. 2" currently is completely broken and unplayable.

The last release that works perfectly fine for me is rpcs3-v0.0.32-16611.

Release rpcs3-v0.0.32-16614 introduces slight flickering to the "Press to continue" text and to the "X button" icon in the game menu.

Also to the video sequence that begins after not pressing any button in the main menu for 60 seconds.

Much worse is that rpcs3-v0.0.32-16614 is also the first release where "F.E.A.R. 2" begins to randomly crash (see log). This can take several minutes in this version.

As said before, these symptoms have become worse in subsequent releases: the flickering is much more intense and the crashes much more frequent. Of course this also the affects the gameplay itself (if you are able to make it beyond the menus without a crash in the first place).

so it is broken since #15623

[TigiHof]

This issue is obviously related to #16008 where the same problems are described for another LithTech engine game. I also tried "Condemned 2 - Bloodshot", yet another game with this engine. Result: same errors! So clearly an engine related bug.

set "SPU GETLLAR Busy Waiting Percentage" to 101 in config yml of the game.

set "SPU GETLLAR Busy Waiting Percentage" to 101 in config yml of the game.

Yes, that works! The game runs perfectly fine with this setting!

[elad335]

Closed because it is known that the default behaviour is a performance hack, though most titles are fine with it and are benefited from it. Should be added to wiki.

[TigiHof]

In what way is simply closing this issue an acceptable solution? Do you really expect every user who wants to play "F.E.A.R. 2" to manually edit the config file?

[AniLeo]

Why can't this behaviour simply be part of Accurate SPU GETLLAR?

[elad335]

Why can't this behaviour simply be part of Accurate SPU GETLLAR?

Accurate GETTLAR is not a setting anymore, but maybe a checkbox can be added to set this value to 101 specifically.

[digant73]

I (as user) don't know why some settings are hidden and/or their meaning/effects. But if they are the only way to make some games properly working then the setting should be available in the GUI. Maybe providing a self explanatory name and description (than SPU GETLLAR). It seems that this setting could potentially fix other games using the same engine, so pretty important.

[elad335]

We have many settings affecting compatibility of games, we expect users to turn none of them on unless they are instructed to by the wiki or on forums or on discord.

[AniLeo]

This should either be a checkbox or just the default behaviour, what's the performance penalty?

[kd-11]

Agree, users should never have to open config.yml unless instructed to do so by a developer for debugging purposes.

[elad335]

@AniLeo Performance panelty is pretty high, for P5 it's about 30% looking at the pr results.
Should be a checkbox, but when it's not set to 101 it should save the previous value on load and restore it on save so it won't override values set in config.
In gui it can be called "Disable SPU GETLLAR Spin Optimization"
