Hey guys, Today, I ran 3DMark API Overhead Test on my Mac Pro 5.1 (6x3.46, 12GB RAM, GTX 970), and was quite dissapointed. My system can handle the DirectX12 Version of the test at only about 9 000 000 draw calls per second. The average number for a system like mine should be way over 15 000 000. I know because the Mac EFI doesn't recognize the GPU BIOS, and communicates because of that at lowest bandwith (PCIe 1.1) with the GPU. My question is: Does this Problem also occur by using a flashed card? And is there any possibility to flash the PC versions of future Mac Pro GPUs just as the current one? For example, if the 2016 Mac Pro contained AMD Fury GPUs, you just could buy a regular Fury and flash the EFI? Or does this ony work for classic Mac Pro GPUs?
