DX 12 and OpenGL Vulkan - akimikage - 05-21-2015 01:59 PM

I'm not complaining about the performance of PPSSPP coz it's really good. I'm just curious if you guys are planning to support the upcoming API's.

RE: DX 12 and OpenGL Vulkan - GamerzHell9137 - 05-21-2015 02:58 PM

Maybe but iirc DX11 wasn't implemented in PPSSPP? Guess its gonna take a while for either of those.

We plan to support Vulkan, we're hoping it will help on mobile devices, some of which have really terrible driver issues sometimes.

DirectX 12, I dunno, maybe? Depends on if there's motivation to do so.

Do you think Vulkan could help getting a significant performance improvement on PC ? Or it will be noticeable only on mobile devices ?

RE: DX 12 and OpenGL Vulkan - [Unknown] - 05-23-2015 03:04 AM

I think desktop drivers are already usually pretty good, at least in comparison to mobile.

It's definitely not impossible, for certain areas / games (for example, maybe it would help situations like God of War by reducing per-vertex overhead - *MAYBE* but not likely, or Tales of Phantasia X which actually runs faster in Direct3D 9 than OpenGL for me.)

By the way, it's also not impossible that we'll do a bunch of work to get Vulkan working, and it'll be slower, everywhere - even on mobile... and we'll find out we have to do a ton of work to even get to where the OpenGL drivers were. There's no sure thing yet, the API isn't even out yet.

Thank you for your reply Smile

My GFX card is a 980ti, I suppose I won't notice any speed improvements with vulkan...

RE: DX 12 and OpenGL Vulkan - GamerzHell9137 - 02-16-2016 02:45 PM

Seems like Vulkan came out today. Woop woop!

RE: DX 12 and OpenGL Vulkan - GuenosNoLife - 02-16-2016 06:48 PM

Not interesting about DX12 because Only W10.
I hope team PPSSPP will work much on Vulkan than DX12 for my ZF2 and my computer W7 Smile

RE: DX 12 and OpenGL Vulkan - fivefeet8 - 02-16-2016 07:50 PM

A couple new Vulkan demos for Nvidia devices including Tegra K1/X1.

RE: DX 12 and OpenGL Vulkan - AdamN - 02-17-2016 05:02 AM

On mobile vulkan requires atleast a GPU capable of OpenGL ES 3.1 which not many device have it at the moment Smile
anyway, vulkan (or dx12) is probably only give performance boost on multi-core rendering, not sure whether it will give much improvement on PSP emulation Big Grin

Most PC users won't notice a great difference on PPSSPP with Vulkan or DirectX 12 since it has at least a Core 2 Duo or Pentium Dual-Core running, and a decent video card. The biggest improvment will be on Android, since the most popular phones aren't capable of running PPSSPP at full speed. Vulkan will be great for future emulators (PS3, Xbox 360, PS4, Xbox One...) and for PCSX2 which requires too much hardware.

RE: DX 12 and OpenGL Vulkan - shinra358 - 02-19-2016 08:58 PM

Sure they will. Nobody wants to stay on 1080p looking at jaggies all the time. It will benefit higher rezzes greatly. And VR 3D performance.

RE: DX 12 and OpenGL Vulkan - GuilhermeGS2 - 02-22-2016 06:18 PM

Sice you have a good graphic card you can play games in 1080p just fine with current PPSSPP version. My GTX 650 is a little outdated but I can even play Midnight Club 3 with 60 FPS 1080p and filters, this game has one of the heavest graphics for PSP. But Henrik already said the emulation of PSP's GPU still needs some work.

RE: DX 12 and OpenGL Vulkan - eghost355 - 03-02-2016 08:50 AM

may I ask if I have a nVidia GTX6800, will I able to enable 3D Vision in Vulkan mode? ('cause I replayed a lot of big titles by PPSSPP because of the 3D support that I will never able to enjoy on the original PSP) Smile
