Recently, I had to deal with an issue where a video card was under-performing. This was an odd issue and was really the first time I have seen this particular problem. I did quite a bit upfront research on this and it turns out there are multiple reasons why a video card may be under-performing. Let’s get right into the causes and solutions for a video card that is under-performing.
Video Card Clock Manually Set Below Standard
This is one obvious thing to look at first. Nowadays, most video card driver software allows for you to lower the clock speeds below standard. Alternatively, the video card speeds can often be changed in the BIOS as well. So, one of the first things to look at is whether or not the clock has been manually lowered in the BIOS or in the video card driver software.
