The only thing that is going to do is to make your graphics card even slower than it already is. Which solves nothing. Both your graphics card and your CPU are weak, so chances are good there is little you can do to fix this issue without upgrading some hardware. Primarily, a new CPU would be a good idea.
As for the resolution, unfortunately the GT 1030 does not support Nvidia Dynamic super resolution, so no, you can't trick it into thinking it's a higher resolution. What you CAN do is increase the in game settings slightly, but all you are really going to do there is shift the bottleneck to the graphics card, which is already probably incapable of performing even minimally well on any semi demanding game titles. My suggestion would be, much as it probably isn't helpful, that you look at upgrading to a whole new platform OR at least try to find a good used A8 or A10 CPU that might help to at least somewhat mitigate some of your CPU bottleneck.
In reality, this is a case where BOTH the CPU and graphics card are bottlenecks, or more appropriately, simply not sufficient for the task.
