As is hardware dependdant i will say that Second solution will be the best, at least until we can find a reliable way of detecting problematic hardware.

I agree. I like the second solution as well. I don't think this is an implementation problem as much as a driver/graphics card problem.

I'm all for a configuration setting. Have the option to pick between hardware emulation, software emulation, or turn it off completely.

Sorry to dig this up almost a week later(was out of town and couldn't keep up) but whenever solution 2 is implemented I'll be ready to test this out to see if this resolves what I was experiencing in Issue 8001.

This may be a red herring, but I noticed all of the reported issues were running on AMD graphics cards. Has anybody with a nVidia graphics card been able to repro the slowdown?

GT 740M here. I didn't create my own issue, just added my experience to Issue 8001 but forgot to mention my hardware, sorry about that.

4.0-3657 RE4 works perfect
4.0-3659 RE4 gets slow down since this build.

I don't know if you can fix it, but well, I'm using 4.0-3657 just for RE4.

I get it in all builds, but in -3659 through -4217 it's a constant 30-50% emulation speed. Prior to -3659 and in every build -4219 and later it's occasional random short slowdowns similar to microstutter, but not your typical microstutter and I don't get microstutter in any games. I stated all of this in Issue 8001 and asked if it's just not fixable for me due to my video card but never got an answer.

It is not fixable due to your video card. In 4.0-3659, Dolphin uses your CPU to create the graphics effect. In 4.0-4217, Dolphin uses your video card. For most people, their video card generates the effect faster than their CPU can.

@skidau what about the reported crash here. We should check that out.

Are we OK with an option to allow CPU Bounding Box?

Issue 8077 has been merged into this issue.

Maybe it's better just to revert this commit?
First dropping dx9 that were fast enough to emulate any game, then x86, now making "old" graphics card users unable to play well with OpenGL above 4217.
I have Radeon HD 5750, my friend has "Radeon HD 5800 series" and emu runs crazy slow above 4217, but 100% speed with our "old graphics card" on 4217.

Those who have "new graphics card" will not even notice any difference between CPU or GPU bounding boxes, when emu run at 100% speed for "old graphics card" users without GPU bounding box stuff.

is not necesary to remove the functionality a simple configuration option top diable it is enought.
JMC4789 I merged the option to the ui on ishiiruka can you look at it if is good for you will make the pull request in master.

rodolfo, for some people, the SW bbox is faster than the HW bbox. For others, the HW bbox is not available. And then for some, the SW bbox is slower than the HW bbox. Having an option confuses things when the emulator should be able to decide which setting is best for the user.

if it possible to change bbox thing at runtime, maybe emu can do test renderings with HW and CPU bboxes and use the one that was faster.

I'm fine with having an option; but I'm not sure if it'll be okay with the Vertex Loader JIT changes (I think we didn't take into account the software bounding box at all?)

Issue 8151 has been merged into this issue.

So I tell my problems here now? o.o

I would also like to add that Muramasa (RSFE7U) has bbox issues as well.
