All games stuttering, even old ones

I have a new Windows computer that is not running any game properly. I already reformatted it because the Windows it came with was full of manufacturer trash. I installed all drivers from manufacturer sites and stopped the superfech perfech thing and also changed the Windows power settings to max performance, used cache dumping programs, Ccleaner, stopped Windows Defender and Windows Update and defragmented the HDD but I'm still facing stuttering in every game.

The stuttering is like, its at 120 fps super smooth but suddenly goes to 10 then back to 120 then 10 then 120 every 30 secs, which makes everything unplayable. In games that allow forced max FPS I force it to 30, but still stutters. I have a Intel i7 8th generation, 8GB ram, Nvidia MX 150 4GB GPU and 1TB WD Blue HDD. It's fairly decent and should be running most modern games at least on low, but even super optimized games like GTA, and old games like The Sims 1 and Minecraft stutter for some reason. What should I do?

By the way, if I go to task manger, I see that the Nvidia GPU is only being 5% used, I don't even know if that has something to do or what not. It has an Intel chipset that it treats like a video card but it stays at 0% usage forever. HDD is only 100% at startup, after 2 minutes it goes to 2% or 3%.

Solution 1:

Are you actually using your GPU?

Open your Task Manager and look at your actual GPU load. This tells you whether your Integrated GPU or NVidia GPU is being used. Your Integrated GPU is part of the CPU and doesn't have a separate monitor, but your dedicated GPU does.

I've had programs where the drivers did not use the correct default GPU and end up trying to run on the Integrated GPU, lowering performance. There are settings within the NVidia control panel that controls this.

Solution 2:

Without proper diagnostics, there is very little anyone can do aside from wild guesses and "Did you already try ...?".

That being said, here are some pointers that may help you find the correct solution:

• Your assertion that CCleaner is in any way related to performance is false. It doesn't increase performance at all.
• The MX 150 is a notebook graphics card, and was not designed for good performance, but rather for delivering acceptable performance with low impact on heat and power usage. Because most people don't play GTA V on a laptop with a low-end GPU.
• Speaking of heat, notebooks are known for having terrible heat conductivity. Try installing an application like MSI Afterburner and measure the temperature. It might be that your GPU is at something like 85°C and to avoid overheating, it throtles down to preserve itself.
