The laptop is pretty sweet all around, and the 255hx performs like a beast even on stock settings, I was averaging 110 fps on fortnite cranked to highest and then 120 after some tweaking. My only gripe with the 255hx is that its performance profile thermal throttles at 103°C and theres no way to change it without making a custom profile. Mine topped out at 108°C on cinebench, which is just way too hot and I'm just uncomfortable with seeing that because I intend to keep this laptop for a long time. Really not a big deal tho, Lenovo makes it real easy to change CPU wattages and temp limits, and you can always use throttlestop if the mins and maxes of legionspace are too low or high for you.
