Acer Nitro an515-43 lagging and stuttering randomly

Man, I don't know what to tell you... I think it has to do with power supply (something with power in any case) and just bad software support/optimization/utilization for Ryzen mobile processors. On 100 % max power management CPU during heavy gaming is 3.7 GHz and temps go up to 98-99 degrees, but on 99 % CPU runs at 1.6 GHz and temps are 65-75 degrees which is just ridiculous. I mean it should be at least 2.0 or 2.1 GHz (basic clock speed without turbo) but it's not and the difference is just 1 %. For some reason CPU is either 1.6-1.7 (99%) or 3.6.-3.7 GHz (100 %), and to it uses  a LOT of power to do that "jump" and that is why it is overheating.

I think it is a software  problem where CPU uses more power then it needs and clock speed goes up for no reason except CPU needs it to achieve some basic actions like loading youtube video (CPU uses all of 3.7 for some basic sh!t). Unfortunately It is not what someone can fix, it's case of badly optimized CPU and cheap cooling system (one heat sink for both GPU and CPU, both fans concentrated only on GPU- which is why this is a budget gaming laptop ).

What I can tell you is this:

1. In power management options put CPU max state to 99 %.
2. Because of these loud fans you should clean your vents and cooling system from dust every couple of months. Repaste might help too.

Recently I opened it and there was a layer of dust beneath the fans and my laptop was just 6 months old. I repasted it and removed the dust and temps went from 89 GPU 80 CPU to 74 GPU 65 CPU (keep in mind this is on 99 % max state). And that is basically all you can do. There is nothing else.

Advice for anyone reading this: unless you can buy this laptop on some big discount (like I bought it) you should not get it. I mean it's not a bad laptop, I can run Red Dead Redemption 2 with 35-ish fps on ultra textures and 1920x1080, but I can not fully utilize this device because of its flaws. I would tell you to wait, save some more money and buy other gaming laptop with better architecture, better optimization, cooling system etc. If it's full price, then it's not worth it.
