Hi 
i have manjaro sway editions, and there are two gpus on my laptop, an intel HD Graphics 520 and AMD Radeon R7 M360. i tried to install some games on my system and everything was fine, i used DRI_PRIME=1 %command% to run games with amdgpu in steam. but i saw poor performance from my AMD gpu, so i went to benchmark my AMD and Intel GPUs. i used glmark2 and unigine-heaven benchmarks for both Intel and AMD, under the same settings. and heres what i got:

you can see the problem, how in the world my AMD GPU score is this lower than Intel !?!?!
unigine-heaven also gives same results, AMD score is 87 and Intel score is 177 
is there something wrong with my GPU ? or its my GPU driver (amdgpu) ?
i’m also not sure if im running games or benchmarks correctly so they use AMD gpu… for example i ran glmark2 for AMD with this command : DRI_PRIME=1 glmark2 --fullscreen .
shouldnt i use DRI_PRIME=1 ? or theres another way to run a process using AMD gpu?
