Pokemon alpha saphire lag spikes

Game can run OK but as soon as I enter a new zone, cinematic or combat I have huge lag spikes (down to 0 FPS).

I did not find anything wrong in your log file. Please wait for a human moderator to assist.

I’m afraid that this is mostly unavoidable on hardware like yours. Pokemon games make use of something called CROs on almost every transition. This basically means that Citra is having to load/unload the 3DS’ equivelent of a .dll file every time this happens, as well as clear the cache. This causes a stutter. You can mitigate this to some degree on sufficiently powerful hardware, but that isn’t possible on your end. You can try seeing if increasing the emulated CPU Clock Speed (Citra>Preferences>System) to around 150% would help decrease the stutter a little bit, but keep in mind that underclocking or overclocking is inherently unstable and can cause freezes. If it starts freezing a lot, set it close and closer to 100% until you have a stable overclock.

Thanks for your reply @SleepingSnake

I’ve read on another thread that with Alhpa Sapphire Citra Nightly 1422 could smooth the lag… so I downloaded it and now I barely have any lag spikes and when they occur, I’m only down 80ish speed an 20ish FPS dor a few seconds :blush: (unfortunately tho, version 1422 doesn’t allow you to overclock the CPU)
