Please help. I installed an Nvidia Quadro k1100m graphics card on my 2010 iMac 27" with firmware designed for Macs. The drivers are fine. The graphics card works fine in High Sierra and Windows 10, but there are some issues: MSI Afterburner shows 0% voltage, and the FPS in games is worse than with a Radeon 5670 with 512 MB. When enabled, it constantly shows 135 MHz. Any suggestions?The photo shows it under load. I've installed different drivers, but they don't help.
Got a tip for us?
