Yes, yes I know I know but..... You miss 100% of the shots you don't take xD

TL;DR, it´s a "nope" for Ray tracing. Don´t know about the other one.

That's a no as well for the same reasons.

Got this in my driver update today :
VK_EXT_full_screen_exclusive
Gives applications explicit control over exclusive full-screen modes (this is for instance useful for HDR support).
Is it possible to have exclusive full screen support in Vulkan now?

Has anyone thought of looking into making an LLVM interpreter and LLVM recompiler?

The fact that RPCS3 runs ridiculously faster on its LLVM interpreter so much so that it outperforms the standard recompiler could mean that Dolphin (Gamecube and Wii have the same/similar PowerPC architecture as PS3) would be able to reach a very significant performance boost,especially if an LLVM recompiler could also be made Android.

I wanted to ask this question/request it as soon as I saw RPCS3 running all that much faster using it over their standard compiler but never got around to it.

The JIT would have to be entirely rewritten. So while what you're asking for is doable, it's probably not going to happen. Also we've had an IL JIT before which had the same idea. It wasn't really faster for Dolphin and went entirely unmaintained, causing a bunch of issues to keep around until we dropped it 2 years ago. So even if somebody was interested, it would be a hard sell.

That's not even a little comparable.

An Intel 80486 and a 9900k are both x86 processors. They should be able to run the same code, right? Not really. Hell, an x86 comparison would have made a little more sense because x86 is just extended on, but would still be pretty bad.


I guess it's worth pointing out -

Dolphin's x86-64 JIT has gone through years of optimization and fixes. Several years ago it was slow as dirt until some very bored compiler nerds started hacking on it and made it faster by orders of magnitude. I think theres a Dolphin article somewhere that highlights this just from 4.0.2 to 5.0 alone.

RPCS3 is a very young emulator. PS3 emulation is not a solved problem yet and they're still finding low hanging fruit to pick to speed things up (And paying developers to work on it full time sure as hell helps). It doesn't really matter whether you used LLVM or a handmade JIT. The results would have been the same.

It's also worth noting that back when Dolphin's JIT was written, LLVM was barely a thing, and wasn't even remotely as useful or as robust as it is today.

Is LLVM very nice for writing JITs? Hell yeah. Is it necessarily faster by default than a mature, non-IL JIT? Not really.

Thanks for the detailed response,oh well. Looking into getting a non-crappy desktop computer anyway which would make things a non-issue.

[Steeloid]

Is there a way to get speaker data working with the dolphin bar or at least have it come out somewhere else so it can be heard properly? There are games that require it at certain points.

[Sorer]

Dunno if it was already mentioned but CHD support would be nice.

To add on the Aspect Ratio feature I made a small list of things I would like to see.

-Custom Aspect Ratio
-FMV filtering (bilinear or bicubic)
-FPS toggle hotkey (on screen overlay)
-Sega Triforce support.
-Static PAL60 option (a bug? it resets to disabled every time)
-More and better shaders and shader system (tonemappers, color temperature, vignetting, etc)
-Surround Stereo; Surround to SRS Stereo, or Stereo to SRS (more audio enhancement options)

[bomblord]

Something I've been curious about for a while, is there a way to directly integrate geometry culling removal? I have an ultrawide monitor and have on occasion forced games to run at 21x9 with the automatic aspect ratio and full screen but (as expected) they tend to look awful outside the 16x9/4x3 area without applying a code to disable culling. Right now it's basically just a google crapshoot on if a code exists for a game or not (I've found codes on reddit that aren't on the main forum topic for example) and then you need to apply the code through the cheat engine and hope it works. Is it possible to integrate some kind of forced culling disable as an enhancement (even if its a major hit to performance) or is each game's culling method too specific to try something universal?

Heck, even some kind of auto AR code application from a known library would be amazing.
