This is not about modding. If you start the NoSteam.exe, click on Graphics Settings and check what Direct 3D Device is selected. See if it's really your dedicated graphics card, which is displayed there. If not, check if it let's you select the dedicated graphics through the dropdown menu. If this is not possible, exit the menu and the game starter, right click on the NoSteam.exe and select the Run with graphics processor" option. From where you should be able to select your dedicated graphics card.

I only have one graphics card that I'm aware of
Most modern CPUs/APUs and mainbords come with an integrated graphics chip these days. Hence my suspicion. In any way, if the above yields no result, we will need a
DXDIAG report from you anyhow, which details what hardware you have installed.
