First of all, thank you for my answer. but.
I am using windows 10. I have two video cards. R9m265x and "Intel". I think I couldn't explain what I wanted to say. There are two options on the screen. due to changing chipset. in high performance option in games. the game crashes. I also want to manually degrade the performance of the video card. In this way, the clock speed and memory speed will be balanced and I guess it will not crash in games. Is something like this possible? As far as I understand, even if you select the external video card and mark high performance in the settings you show, the "Microsoft" control panel gives priority to the settings in my screenshot selected from the advanced power options.
What I want to do is: I will choose the high performance option from the settings in the control panel and the settings in the screenshot you showed. then I will manually balance the clock speed and memory speed so the game doesn't crash. Because I don't want to pay the new chipset fee. In our country, the Turkish lira is 9.3 times lower against the dollar.
