I don't understand to overclock it, because I never did that on my computer.
But I want to add information according to the image below:
When I select the options: Standard Nvidia, Alternate Nvidia, Standard Nvidia with exe rename, Alternate Nvidia with exe rename, Standard Intel, Alternate Intel, it will show the same thing, which is the grid display when starting the MTA.
However, when I had the Standard Intel with exe rename option, everything felt normal and smooth.
I don't know what's wrong with my MTA. This has happened for about 6 months.
