It only works properly with Direct3D 11 backend, it's not powerful enough to push 2x on most games and it has driver bugs that won't be fixed because Intel ended support for it a long time ago (that's why you're seeing glitches). To make things even worse, a security update pushed by Intel on early 2020 had a huge impact on performance, which already weren't that good to begin with.On the GPU issue, I understand. But the point itself is not about that, but about the difference in performance between both versions of Dolphin that I have used - and, of course, on the same hardware.
So yeah, there's not much you can do. If you don't care about the security exploits you can downgrade to driver version 15.33.48.5069 or earlier, to reclaim the lost performance. Even then, it won't fix the graphical glitches you're experiencing...
Big question here is: Why does the newer 5.0, from which a minimal gain would be expected, have glitches and lower performance than the older version 3.0-410? Even because in this 3.0, there are no graphical glitches - not even in resolutions above 2x native - just lag spikes - which was expected and, as I said, completely acceptable! And the hardware is the same, with the same CPU, GPU and RAM. What changes is the software!
So, unless someone comes to me and says something like: "Newer versions of Dolphin are less tolerable to older GPUS like the Intel HD 4000, while older versions can handle such GPUs better", I can't help myself to convince otherwise, as far as the difference between the versions in practice is so evident.
So then I'd go back to version 3.0 with its messy motion plus, and try to get by with various control profiles, until finish the game!
