@hilderstone Your laptop is definitely using the iGPU in your screenshot. Did you by any chance minimize the game before looking? That could and should prompt a laptop to switch to integrated graphics. So could playing on battery, which I meant to mention before; if you're not playing with the laptop plugged in, please try that first.
Otherwise, you can force Windows to use the Nvidia card. Hit Windows key-i, select System > Displays > Graphics settings, click Browse, choose TS4_x64.exe, and select the high-performance option. This should override almost any other source trying to select the integrated chip.
Please also remove ReShade, at least for now. The fact that lowering object quality helps is odd, but maybe less so if something wonky is happening with a texture overlay.
