"Sync to Exact Content Framereate" and PAL60 EU games problem

[Jobima1st]

last dolphin core with "Sync to Exact Content Framereate" set to "on" and Eu games that has PAL60 mode (like "The Thousand-Year Door") will make the game run slower (50 fps) if the user select 60hz inside the game!

IIRC it was fine before

You need to provide a log. Also when you say fine before, when was the last time you updated dolphin?

with fresh retroarch

don't remember, I also dont play with dolphin core that much even if I do update all the cores from time to time

Nope: #310 , basically if it's a GC PAL game, the core will be stuck at 50 Hz, no matter if the game has a 60 Hz mode (Super Mario Sunshine, F-Zero GX, etc.) or if 60 Hz is even required (Geist, Zelda Collector's Edition, etc.).

I was working on a fix: bslenul@f8a2d71 but wasn't sure if there's a better way of handling it and was busy with IRL stuff so never submitted it. edit: I had an alternative approach using GetTargetRefreshRate() also.

Does the standalone handle this use case?

[bslenul]

Yes, absolutely no issue on standalone with the different refresh rates at runtime.

[cscd98]

In that case I (or somebody else) will have to track down where that is handled and retrofit in to the libretro code. Just gotta find the time.

I'm wondering if this is the same issue preventing a cheat code to work correctly in the Dolphin core, even though it works in standalone Dolphin. I submitted a PR with it for the standalone Dolphin a few months ago, and all it does is cap the speed at 30 FPS in Mario Kart: Double Dash and Mario Kart Wii: dolphin-emu#13795

When enabled, it works perfectly fine in standalone Dolphin (notice that the FPS drops to 30 once the BIOS intro is complete):

But in Dolphin core, even with it correctly enabled (see the notification "1 cheat(s) enabled" confirming it at the beginning), the FPS remains at 60:
