I have tried it all bt it dosnt affect my game speed
Well, final suggestion I have.
When was the last time you properly de-dusted your laptop? It is imperative that a laptops heatsink be regularly cleaned. If I don't clean my laptops heatsink out at least once every couple weeks, my CPU hits an extra 20C+ higher than normal, causing downclocking leading to frame stutter.
Even a thin layer of dust causes this issue for my device, if you have access to compressed air (Compressor attachment or canned) I recommend taking the bottom plate off your laptop and dedusting the heatsink. (Make sure the FAN does NOT spin! This generates current back into the board, just hold the fan still.)
If a thorough heatsink cleaning doesn't improve anything, I'm out of any likely ideas to help you. Usually when your FPS is low, and doesnt change with graphical settings that indicates a CPU issue, for CPU load does not change with graphics settings. (Hence my thought of CPU overheating.)
