I have had this issue since day one and I have pinpointed the issue. The r9 m275 in the Y40-80 performs under full performace up to 75C. Once it hits this temp it immediately down clocks fromm 925/1000 to 300/300. 75C is FARRR to low for the GPU to begin termal throttling. Lenovo needs to address this issue with anupdate if possible.
