UI on all platforms(including NewUI!): Add options to change FramebufferCPUConvert

[thedax]

Needed for non-NVidia GPU PCs and mobile devices in games like Danganronpa(for whatever reason, it crashes for Intel/Amd/Android if CPU Convert isn't on, and it shouldn't). Not everyone roots or wants to root, nor edit an INI by hand often.

[thedax]

I had to move Display raw FB to a different page so it could fit the convert CPU option..

BTW , it would nice to grey these two framebuffer options when buffered rendering OFF (but i'm busy other stuff so cannot work on this )

[thedax]

@raven02 : This is my first time poking around in NewUI; does it have functionality to enable/disable specific items after being added? If it does, I certainly missed it..

[hrydgard]

@thedax , not easily right now, I'll have to think about how we do that best.

[hrydgard]

By the way is the CPU conversion a big speed hit on nvidia? We should probably default it to true as it appears to be required on most non-nvidia chips...

[thedax]

@hrydgard : Um, I haven't noticed any real speed issues with it on, but I don't really think it does anything on NVidia anyway, so I don't -think- it would hurt to have it on if FramebuffersToMem is also enabled.

Edit: I did a quick test with Danganronpa 1 with both Framebuffer options on and then only FramebuffersToMem on and there was zero speed/VPS difference(tested by looking at the Speed when holding down tab), though we do have to remember my PC is pretty beefy..

[hrydgard]

So do this then: Set to true by default, and remove the option on mobile platforms using #ifndef USING_GLES2 . Then I guess slow nvidia users can try to turn it off, and it "just works" for everyone else.

[thedax]

That should do it. Let's hope it doesn't slow down mobile too badly..or is it time to consider making the framebuffer options an all in one solution(e.g. one button rules them all)?

[hrydgard]

Yeah, I think so, unless we can get the conversion that doesn't involve the CPU working on mobile.

We now have vendor flag setup in framebuffer , may be we can somehow enable or disable this option based on vendor flag however i don't pretty sure what would be the matching . As lots of users in other forums keep asking WHEN should this option be ON or OFF .....

[dbz400]

On my Nvidia system with GTX690 , CPU ON is around 1/3 faster than OFF . Therefore i suggest to be always ON

• YS 7

With CPU convert ON , 696 FPS
With CPU convert OFF , 445 FPS

• God Eat Burst

With CPU convert ON , 876 FPS
With CPU convert OFF , 619 FPS

• Danganronpa

With CPU convert ON , 1456 FPS
With CPU convert OFF , 1388 FPS

Thanks for testing. Then we have the right default now :) And can probably get rid of the other path. Although it is a bit surprising.
