even though my iMac 9,1 doesn't an AMD GPU but I downloaded MouSSE and its a kext if those with AMD GPU want to try it out while you add it to your patcher couldn't you use like kext beast or kext utility since it is a kext for those who may not be comfortable with using the terminal
It's not just for AMD GPUs. Some apps like World of Warcraft.app don't work without SSE4.2. Of course, if you haven't run into any problems without it, and then you install it, then you won't know if it fixes things in the future - things will just work.
While I did help achieve acceleration on Catalina, I haven't worked with dual GPU systems at all (just my trusty 2010 MacBook, which has only one GeForce 320M). But I know that @dosdude1 has this page which may help you disable the GPU. After that, the legacy video patch should work with your Intel GPU.
There is no full installer of any point release beta, only delta updaters. I installed 10.15.0 final and then updated over that by manually extracting the update package with
pkgutil --expand-full, and then copying it over the installed system.
I have installed MouSSE I don’t know kextbeast I used kextutility which I can upload in the morning

Yes except touching extensions string. SIP is definitely disabled )
The emulator is more for apps and drivers that use SSE4.2 without checking that SSE4.2 exists. Now, if there was an app that checked those flags and decided to quit because the flag is missing then we would have a problem.
Same thing. Hangs on restart. So waiting for corrected one version.
The short answer is no. The scope of MouSSE is quite narrow - it doesn't even provide full SSE4.2 emulation, just enough to make the AMD Metal drivers work. SSE4.2 comprises 7 (technically 6+1) instructions, of which MouSSE currently emulates 2. SSE4.1, which I understand to be required for High Sierra and up (maybe even Sierra, I haven't checked), comprises 48 instructions. A full SSE4.1 emulation would be a huge task, and there's a good chance that it would be slow enough to create a poor user experience. That aside, part of the reason MouSSE works is that it's primarily trying to assist another kext, and if MouSSE can load before that kext, both can do their jobs. If SSE4.1 is part of the kernel itself, MouSSE would never even get loaded, and could be of no benefit.
You've discovered one of MouSSE's current shortcomings. I haven't yet found a way to trap the CPUID instruction without adding undue overhead to the system, and as a result, CPUID won't reflect any SSE4.2 or POPCNT support (unless the CPU already natively supports it, of course). For its current narrow purpose (AMD drivers), that doesn't seem to be an issue - they don't check for SSE4.2 support first, they just use SSE4.2 instructions. In any case, I'm not sure I'd add the SSE4.2/POPCNT bits to CPUID without full SSE4.2 emulation anyway - if it becomes an issue, I'll dig further into it.
