Double check the CPU is still running at full speed. Without a battery most mopdern laptops will throttle CPU (and maybe GPU) performance.
Also there’s no reason to remove the battery if you can cap it’s charging. 80% is better than 100%, but if it’s plugged in 24/7 cap it as low as it will let you. But 60% is even better than 80% for health. And any cap below 100% severely reduces the chance its battery will expand.





OP has an Nvidia GPU, presumably running their proprietary drivers. AMDs open source drivers vs the hemi forum have nothing to do with this.
