render offload graphics with gpu? - zehel - 03-24-2013 06:33 PM

Since emulation is putting a bigger strain in cpu maybe we could lighten the load by using the gpu for background graphics or even lessen the color depth for better performance...

Im sure optimisation is being madeSmile

Wouldn't help. The only way to do that is converting from 24bit to 16bit which would make speed if not equal a tiny bit worse.

I wonder if emulating B&W colors only will improve vps :/

Nope it will make it worse, you involve a colorspace convertion there.

It's actually easier to render stuff as it is given than converting it because that adds extra processing.

Making it 16-bit / 24-bit / whatever is only useful for reducing VRAM usage. But for that, we could just use compression (like ETC1).
