Jarring A/V hiccup problem - SOLVED

RetroArch General
#1

Everything runs perfectly smoothly on my system for a while, but always eventually RA seizes up, the frame rate drops to like half of normal and the audio is horribly slow and crackly. This happens for like a couple seconds at most but is incredibly distracting. It happens seemingly regardless of core, vsync settings, audio driver, or version (32 or 64 bit).

Is this a normal thing? I don’t have the best hardware, but it’s not the worst, either. I have a 2.2 GHz dual core, 4GM Ram, and a fairly crappy Nvidia Ion 9300. I’m running Windows 7 64 bit.

How are people getting RA to run smoothly on the freaking Pi but I can’t get it to run smoothly on my computer? I just want performance equal to what I get with standalone Nestopia, with the awesome shaders and the convenient interface of RA.

Which shader are you using?

#3

Just scanline.cg or CRT-easymode.cg, with default filter set to nearest. I’m going to try the suggestion you made in the other thread, thanks!

Ok, I’m looking around for audio latency but I don’t see it anywhere in the options. Is this buried in the config file somewhere?

SOLVED

I believe I solved this - there was a setting in my graphics card called “threaded optimization.” Leaving this at ON or AUTO resulted in abnormally high cpu usage and occasional jarring A/V hiccups. Disabling threaded driver appears to solve both issues. I play tested for a couple hours last night with no noticeable hiccups!

What’s strange is that Nestopia standalone didn’t suffer any problems with the same settings. For some reason, retroarch has problems with “threaded optimization.”
