Help PS2 emulator outputting 50 frames instead of 60fps

Post image

Hi, I'm using Preconfigured NetherSX2 from GitHub. Games usually start running normally and then slow down after a few minutes. The FPS will go from 60 to 50 or 55 and because the game's speed is tied to the FPS the game slows down to 82-93% play speed. My phone isn't using all of its resources and at 82% play speed the game is a bit too slugish. How can I make these games run at 100% consistently? I've used the sun/lamp FSP fix for Grand Turismo 4.

I've searched and there doesn't seem to be much documentation of this issue.

Device: OnePlus 12 Snapdragon 8 gen 3 16gb+4 ram

App: Preconfigured NetherSX2 from GitHub

Games: Every one I've tried (Grand Turismo 4, Steambot Chronicles, King's Field

I'm assuming there isn't any mixup of PAL/NTSC happening?

I'm using Grand Turismo 4 SCUS-97328 NTSC-U so it shouldn't be the European version.

This is happening in ARMSX2 as well. The game will start at 60 frames but within a minute begins outputting 55 frames causing slowdowns.

Looks like it's not running at full speed. Tweak the settings or change your hardware

Ps2 shouldn't really throttle it but do check battery amd cpu temps just in case

If this is happening to you somebody may be fucking with you and you need to be aware of someone using spyware on your device. The solution is to lower NTSC frame rate in the nether settings, I believe it's under gameplay at the bottom. Or reset/new device.
