Understanding Graphics Benchmarks

[will_s]

Disappointing in my GPU benchmark. The card is a Zotac 2080ti amp and 3D score is 14689 and 2D Mark 717 ( wierd )

I see when running DX12 it gives me a 38% reduction because I cant run as my monitor is 3440x1440



Surely my graphics card can run that mode ?

I just cant understand

The DX12 test was designed to run at 4K resolution (3840 x 2160 pixels).
As your monitor isn't 4K it will still run, but at a lower resolution, which in turn increases the frame rate. In an attempt to make the results comparable we penalise the result when running at a lower resolution.
