Speed throttling question
Hello ^^ , I'm a new user of the emulator and find this emu amazing so I registered in hope of helping the community to further develop this emu.

Anyways, I'm still a newbie with the functions of this emu so I want to ask how to throttle the speed of the emu higher than twice it's speed. I can run it twice the speed but won't get any higher than that. I've edited the graphics settings and set the FPS to 300 but still no luck. Changing the "Speed" to "fixed" only throttles it to 200% and pressing "Tab" does the same.

I don't think it's my rig coz I've tweaked every settings that could give better performance and it's still capped to 200% or is the emu capped on running 200% speed ?

Gamers cannot gain anything without first giving something in return, to obtain something of equal value must be lost that is gaming world's first law of equivalent exchange. In those days, I really believed that would be the world's one and only truth.

RE: Speed throttling question
Firstly, are you using the latest dev build on the buildbot?

http://buildbot.orphis.net/ppsspp/

Secondly, ensure you're not forcing Vsync or anything like that in your NVIDIA Control Panel.

Setting the Toggle Speed Limit to 300 would net you a top speed of 500% in Fixed mode, and pressing "Tab" (which is the Unlimited Turbo button) should net you even higher results.

If in doubt (whether the problem is in the emulator, or in your NVIDIA Control Panel settings), run the cube.iso program (the one with a spinning cube that comes with the emulator, located in the ppsspp\demos folder) and try both the turbo functions there.

You should be able easily surpass 200% speed in that very simple program. (see attachment)

I'm an idiot ~,~ . I forgot that I've left vsync to adaptive to prevent screen tearing. Thank you for the help solarmystic
