PSX stuttering in some 3D games

Thanks for checking - it's great that we narrowed this down!

I'll probably try to fix this for good by adding a proper core vibration option to lr-pcsx-rearmed, was looking at the code and it didn't look particularly daunting (famous last words).

I'll see where that takes me in the coming days.

Best.

@pjft that would be really cool! Would you have to write the code to kill it for each specific controller type though? I am assuming it would be a core option that could be saved for all games? This would be really cool if you could figure it out! Good luck!

I am just going to use a usb bluetooth so i can keep the rumble. I wish the rumble was stronger though. It is really weak on my ps3 controller.

Submitted a PR for adding a Core Option for this.

Best.

@pjft thanks for figuring this out so quickly! I am not an expert on Themis coding, but it appears the code will work for all controller types correct? Xbox 360 and PS4? The pr states it will fix it for PS3 controllers...thanks

@TMNTturtlguy ah, sure, apologies. It'll allow you to disable vibration for any kind of controller.

I was under the impression, from this and the other threads, that this only happened on PS3 controllers over the RPi's on board Bluetooth.

Hence the description.

Would love it if you can test it afterwards - as well as if someone who does have vibration can test it as well to make sure it works as intended. I don't have a controller with vibration so can't test, other than noticing the stutters:)

@pjft I will definetly test it! Unfortunately the Xbox 360 build I have now is going to my nephews tomorrow and they are taking it 4 hours away....so if I am able to get the update in time we will test it. Otherwise my next project is for myself with PS4 controls, so I will test that as well!

@pjft The PR was accepted and merged. I had to update from source. I tested it out with the xbox 360 controllers and it appears that it fixed the situation. I was only able to implement the change and test for a short time, but I think it works well. I did notice some inconsistencies in saving the change to core. Could be that i have several games that have their own game core changes, but it appeared when I made the change and saved to core, it only saved to about half of the games....the other half i had to set manually and create a game core for. I didn't have time to test further, as it was a gift that I have now give away :( Bottom line, looks like it worked well on my build. I will be sure to test on my next build as well. Thanks for the hard work!

@TMNTturtlguy Not a problem, it should be good to the best of my testing abilities. I did not make a lot of changes as well, so its impact should be fairly self-contained. As such, I don't see how it would have affected the saving.

There's an option to have game-specific core options saved, maybe you had some of those set? I don't see why that would be the case, but it is a possibility. If you do have created a game core for some of your games, then yes, the is the case. If you don't, then saving the option will affect all the games (as all read from the default options).

Cheers! Thanks for helping narrow down the cause for this!
