I see some people run their game perfectly fine with lower dx levels on a game that requires higher dx level.No, it's not possible technically. Even though the GT 320M supports DirectX 11, the feature level is only 10_1, which can create issues with many DirectX 11 & DirectX 12 titles.
;-; alright thanks for helping out. ^^DirectX actually maintains backward compatibility with previous versions, so DirectX 12 is backwards compatible to DirectX 9.
There is a chance that your video card will not be capable of running a game that requires an advanced Pixel Shader model, even if your card meets the minimum DirectX requirements.
