Laptop GPU dramatically slowed down

[RaiAzzy]

I've been using my current laptop for a while (HP Pavilion G7-1200) and everything was going fine until I installed Ubuntu. Before installing Ubuntu, the integrated graphics got around 30 & 40 fps in games like Minecraft. After using it with Ubuntu for a few months I decided to switch it back because I missed gaming and even after downloading all the drivers, the graphics would give me best of 8fps but hover around 3 & 4 fps. What's wrong with it!? I've installed a new hard drive, upgraded it from 4gb ram to 8gb ram, cleaned out the fan, and replaced the thermal paste. What else can I do?

 

Thanks for your help and suggestions.

Make sure you have the GPU drivers installed.

Is the gpu thermal throtteling? Check with something like cpuid hw monitor. Also check your windows power plan.

To be perfectly honest, there's not much you can do to improve performance at this point without just buying a new laptop. We're talking about a business laptop from quite a few years ago, that was never designed for gaming. Even in its time, it was considered 'medium to low end.'
