Moreover in Catalina everything works but the wx7100 Has lower performances compared to the HS test while was working

No everyone,
We're not doomed...yet
I am able to boot Mac OS 11 on a 2011 iMac. I see the IOsurface and AppleIntelCPUPowerManagement.kext is still there. So maybe the hd3000 Kext will work. I'm booting over USB 2.0 so everything is slow at loading. Nvidia Kexts are still there for Kepler.
Backlight Kext needs to be reworked for Mac OS 11.
Full brightness isn't correct anymore.

UPDATE: i figured out that blugging and unplugging the minidisplay port makes The internal display work again in HS. So the machine is working, but can anyone help me to figure out how to avoid this?
Hi everyone, I just upgraded my gpu to tested working Nvidia K2100m pulled from a Dell, but upon install I am getting no display signal and also my motherboard is only showing 2 LEDs, does this mean my GPU is bad or that the bios just isn’t compatible? I ordered a CH341A programmer and will flash the bios tomorrow to see if that has any effect.
You can't just plug the card in. It won't work. You need to flash the BIOS. There is no way around that. Did you look at the first post? Everything is there.
NOTNICE (and anyone else interested)... I recently discovered something about this quite by accident. As I previously wrote a couple of days ago I was able to get my 2011 iMac 27" working with a WX7100 by following the updated Catalina Loader guide posted by @Ausdauersportler (Post #7323). After shutting the iMac down and removing the OC USB drive in preps to make the PolarisBoost mod, I started the iMac up without the OC USB drive inserted. To my surprise, the iMac started up without issue directly to my desktop. The screen remained black until a couple of seconds before the desktop appeared. Everything has been working normally in this fashion without the OC USB drive inserted after multiple restarts. [Note: I have not yet made the PolarisBoost mods for the sleep issue...and I can confirm the slowdown problem exists on my machine. My Valley score and FPS were cut in half after waking form sleep].
So, to make the long story above much shorter, I am able to successfully boot into the latest version of High Sierra without using OpenCore despite the fact I used the GOP VBIOS to flash my WX7100. Unfortunately, I don't have a full technical explanation to offer.
Is this with the AppleGraphicsControl.kext installed? If so, this is normal
It is with the AppleGraphicsControl.kext installed using the file from your previous post (#5887). Thanks @highvoltage12v!
I am very happy to have purchased the WX7100! GPU Heatsink temps during normal everyday use average around 37-38 degrees C and running the Valley Benchmark I haven't seen it get above around 57-58 degrees C. (Using Macs Fan Control as discussed in the Catalina Loader posted by @Ausdauersportler.) Hoping to start my Mojave installation experiment in the next couple of weeks.
The iMac late 2013 is the one that didn't make sense to me. Haswell chips and running the same GPU as the late 2013 and mid 2014 macbook pros, which are supported. To me it looks like a cut for anything non-retina.
BUT...the 2013 (and later) MacBook Air doesn't fit with that either. Confused...
I'm quoting my message from the Mac OS 11 thread here. It's mostly good news. Just don't know how to get non Apple Kexts to load, most likely an OpenCore issue.
Also there are some EG2 ROMS in OS 11 worth looking at. I'll have to dig them up for everyone.

What could this be? GPU or VRAM? This is a picture of a flshed GTX 780m, it worked for some time and at a sertain paint it just did this.
looks to me like bad vram perhaps.
I hope/presume you also cooled the vram chips on the backside, like I did with my GTX765M mods.. ?
I highly recommend cooling the vram on all chips if possible btw..
I don't know if the RAM were cooled or not, this is not my card. Hmmm could even be a 860m. I planned to make some RAM-Cooler for my K1100M an GTX765M i got here. Do you have come pictures of it? How thick is your coolingmod?
Til today i did not changed RAM-chips on PCB's. I will see to find some on fleaBay.
This is on the front page! We cannot mark everything on the first line in bold red letters - the page still has a lot of content and people simply must carefully read it, make a plan of the complete thing and write the plan probably down before ripping apart a piece of hardware. You have to make your own Lego alike plan for your own project!this must go on the front page effective immediately. thanks
2. Native brightness control is available for the Quadro K1100M and K2100M as well as the AMD cards using a combination of custom VBIOS and OpenCore. See this post for information about using OpenCore. A guide to using the provided OpenCore disk image by @Nick [D]vB has been written by @herrdude on THIS POST.
You can update the Lilu and Whatevergreen, but updating OpenCore within the Catalina loader is still a riddle not really solved.
If you want to test we are happy to hear the results
guys, is it possible to install windows 10 on iMac mid 2011? Using bootcamp.
My configuration: iMac mid 12.2, core i5 3.1 Ghz, 16GB, SSD 512Gb, GeForce 765M 2Gb.

Officially not, with a patched bootcamp yes. The internet search machine will show you the way.
if it’s not ok to post this here let me know and i’ll take it down
my 780m took so long to arrive from china that i’d already decided to get rid of my imac
i’ll be posting it or the 770m that’s in the imac on cl in lower mainland bc if anyone nearby is interested i’ll give a fair deal

Hello,but updating OpenCore within the Catalina loader is still a riddle not really solved.

I've been updating it regularly for a long time with these releases https://github.com/williambj1/OpenCore-Factory/releases
Good day / evening
PS: All on my EFI partition of my system SSD.

Yes, this is no problem and well known. But we use for a good reason the Catalina Loader installed on an external device. If something is going wrong or you want to experiment on the settings you simply build a second SD card and have the fall back by hand.
Having a non working EFI partition on disk is a real joy
