Monter Hunter Tri - unchecking Skip EFB Access to CPU makes the game unplayably slow even on the strongest of computers only on master, not Ishiiruka

What's the problem? Describe what went wrong.
Since Monter Hunter Tri is barely playable due to the exagerated bloom effect caused by Skip EFB Access to CPU and if you uncheck it the game goes from 50 to 1 fps, I think someone should investigate why with the Ishiiruka builds you can uncheck Skip EFB Access to CPU with almost no performance hit and finally emulate properly the game.
Is the issue present in the latest stable version?
yes

In Latest Master on Vulkan, I believe Vulkan can actually run it full speed.
the answer to this is that Ishiiruka has a fast EFB access option that causes the bloom effect to desync from the frame it's drawn on. This doesn't cause any serious errors (usually it just means teh bloom is slightly behind the actual movement of the camera) and because it's given more time to render, it's not slow. Maybe there's some other optimization.
Master has no intention of merging a hack like Fast EFB Access at this time, but, I do believe with proper optimization to certain EFB Access patterns this could be made faster, though, it'll never be super fast.

On master unchecking Skip EFB Access to CPU in Vulkan doesn't cost so many fps, but also it doesn't render properly game-graphics (bloom is gone, but there's some kind of "washing" effect on screen)

I guess Vulkan's optimized EFB accesses break this game on top of it.
I don't think Fast EFB Access will ever be a part of master. Not sure how to get a game like this working correctly without asynchronously doing the EFB Pokes/Peeks considering how rampant they are. May be a job for second level fifo?

Thanks to the videocommon unification I think that this issue can be closed...
