'Skip EFB Access from CPU' Hotkey

03-03-2015, 01:41 PM #1

EFB Access from CPU can kill the speed of Dolphin (for those without a top CPU), but it's necessary for some features.
It would be perfect if we could enable it where it's needed and disable where it's not with the press of a button.
As far as I know the Development Team don't want to include (are against) a "Skip EFB Access from CPU' hotkey in Dolphin.
So I want to include it in a version of Dolphin for myself, but my programing skills are too weak.
I tried to find where to include it in the source code with no success.
Can anyone tell me where to include it? How to implement it? It seems not to be that hard. Add about five lines to the code?

Thanks.

Do you want it for mario galaxy?You dont exactly need a top of the line cpu using the latest dev and hle audio.Also don't use more than 3x internal resolution with that gpu,even a 560 ti will drp some frames in this game at 3x. And try using open gl.

In SMG is it really gpu releated when framerate drops at higher res wile gpu usage is not even close to max ? Wouldn't better gpu do same exact thing ?

GPU <-> CPU communication is the holdup in a lot of games. Super Mario Galaxy seems to slam GPUS with something, but I'm not exactly sure what.

But the Development Team doesn't want to include such a hotkey in Dolphin.

Sounds like a nice feature for Tino's unofficial Ishiiruka build.

There's a difference between "have not done yet" and "do not want to do ever". It shouldn't be too much of an issue to code, but it easily be the case that the devs have just worked on more interesting things. Hotkeys are not exactly everyone's priority one.
