Performance issues any build past 5.0 stable

[patracles]

Hello all,

I recently got back into Dolphin after discovering the Bluetooth pass-through stuff and obtaining a new GPU. I had installed 5.0 stable, and was running The Last Story at 4k beautifully (seemed to be locked at 30FPS but still absolutely fine, zero FPS drops). After wiring up a Wii bluetooth adapter, I realized I needed a newer build for that functionality. Downloaded most recent dev build, and now all games run terribly in full screen (Skyward Sword/The Last Story both running at < 10 fps). Any ideas what could be the hitch? I notice that the dev builds don't "install", rather they just unzip as a directory with the dolphin program. Is there a recommendation on how to cleanly move from one build to the next? The only difference is that before I was using a wireless xbox one controller, now using the BT passthrough. I really don't think that should impact the performance in this situation.

Computer specs:

Core i7 2700k OC'ed @ 4.6GHz
Geforce GTX 1070
16GB of PC3 2133 memory

Any advice would be appreciated. I've already looked through the performance guide, everything is set accordingly.

can you please bisect from 5.0 stable to the latest dev build to find out which build caused the slowdown?

Use this tool if you don't know how to bisect

So this is super bizarre, I reinstalled 5.0 stable to begin bisecting, and now even that has the same problem. Went to run The Last Story with my Xbox controller as before, getting pitiful performance. Nothing has changed on my PC other than one GPU driver update.

Controllers shouldn't have any effect on performance, so it sounds like your GPU driver update is the culprit, then.

Post pictures of your Dolphin configs please, that will let us see if you have an issue in Dolphin.

Also setting up a high performance profile for Dolphin in the Nvidia Control panel is a great idea

8x SSAA… assuming you'll be running at your fullscreen resolution (4K?), that's probably something your GPU cannot handle, because that's insanely demanding.

Also, XFB can be disabled if you don't need it. It'll be auto enabled for games which do need it.

Turn SSAA down to 2x or 4x at MOST

8x isn't reasonably attainable on any hardware. Not sure why we expose that.

Yeah , 8xSSAA + 4k will almost equal to 8k resolution which is way too much for GTX 1070
Why not just use 4xIR (Internal Resolution) + 4x MSAA or 6xIR + no AA
Btw , Directx12 is way better than OpenGL , especially when you play game at 4k
In most case, AA will help you get rid of jaggies but it also has a side-effect : blurry graphic
I never use anything higher than 4xIR so I don't know but 6xIR + IshiirukaFX (optional) should work best for you

Thanks for the input guys. What's odd is I swear those are the settings I was running at before the issues started. It makes sense though that that would hose the performance. If I set my IR to 4x Native or 6x Native, what should I set my fullscreen resolution to? Still 3840x2160?
