Check my spec below, its an awesome laptop.
I use it happily to play DCS at 1440p 40-60FPS (actually 2560x1940 with the MFD output) because I dont have a good desktop and got this specifically for what you got yours for and then some video editing, but being able to get back into DCS has been a nice bonus , Biggest issue I have is the hard drive is half gone with DCS, office and a couple misc tools so you would be better to get a 1TB NvMe drive than a 256+1000gb.
I kicking myself for not spending the extra on the RTX 2060 just because more FPS and only having 2 RAM slots I have no ability to upgrade RAM easily, but honestly the extra HDD is probably the only think it really needs for comfortable gaming. At 1080p I was getting 50-70FPS.
By default you want it on power to run or it handicaps the thing terribly and it does get noisy with the fan and as suggested above 'hot' though the cooling on this laptop is exceptional.
