@Dominus, can you also help reporting the bug to HomeBrew for the next SDL bottle to include the fix? Perhaps you can also do it for MacPort. The libsdl Portfile from MacPort is even more pristine than HomeBrew. Or maybe MacPort simply prefer "SDL1.2 must die!" 🤣.

And the DTK was also only on remote control, so that part did not change. The DTK was right in every sense by forcing HiDPI handling even through remote control. It was made to behave just like MacBooks with retina display to force the early access development to focus on HiDPI aspects of software …

That's what I have been yelling *Display Scaling* . If you do remote desktop or Hackintosh on VM, then there is literally no display scaling in action. If it drives a local retina display, such as the MacBooks, or a 8k/4k panel at 27 inch on the MacMini, then I think you will see the problem. This …

But all this with output surface, your opengl fix doesn't seem to fix it, only makes it "different" to what was the problem before. So how did it look when you removed the OpenGL fix? I think that is "the fix", so I also have this to scale up all VGA games nicely. windowresolution=2048x1280 scaler= …

Apple M1 rosetta2: normal 43, dynrec dynamic_x64 110 pristine r4459 Interesting, I believe the Rosetta 2 should be dynamic_x64 compiled as x86-64 and translated. So native AArch64 dynrec is actually faster, that is yet another surprise. Benchmark PCPbench: iMac Pro 3 GHz, Core 10 Intel Xeon: 167 …

I have to say that CPU core dynrec on Apple M1 is simply amazing. Though it is not faster than dynamic_x64 with Rosetta.2 translation , being native AArch64 is always more future-proof. A similar concern on dynamic_x86 was there before the CPU core was overhauled to be 64-bit ready. Kekko's Voodoo …

I am still puzzled why dynrec targeting x86_64 is so slow compared to dynrec targeting AArch64. I wouldn't have thought dynrec was capable of matching QEMU TCG performance in AArch64 and apparently I was wrong. I am curious if this would be the same between DOSBox dynrec and QEMU TCG on other non- …

The hack didn't touch anything on core normal, I believe. Normal should just be the same and dynrec does not work on pristine r4459 without the hack. So the scores are 105 and 0 if you would complete the chart. I would be more interested to have more recent x86 implementation such as Ryzen 5000 and …

This is a simple patch to enable CPU core dynrec for DOSBox SVN on Apple M1. The solution was extracted from dosbox-staging PR #1031 by @kklobe , simplified to be less intrusive on DOSBox SVN at the expense of disregarding for source portability. It also fixed OpenGL output on Apple M1 but only …
