Yea, unfortunately, laptop video cards are not that great. However, have you tried turning down your settings to say, medium? This may help out alot, and the game still looks amazing. You could try fullscreen at that point to see if it will run without crashing. Do you know where to switch from Windowed to Fullscreen? Also, you say when you are playing in windowed mode, you have a very tiny window. Do you mean the window is only filling up a part of your desktop? Have you tried adjusting the size of the window? Usually when it plays in regular windowed mode, it takes up the full desktop / screen, minus the bar at the top, and the taskbar at the bottom.
Like I said, I run the thing at 1368x768 with everything maxed to ultra except for anti-aliasing and ambient occlusion which are low and on maps like Hoth I get 60 - 70 fps, space battles I get 70-80 (even 100s) fps, and on the map of Endor I get 55-60 fps even in heavy situations. I even tried medium settings where everything then just runs flawlessly at over 100 fps but to no avail with full screen. I know where to switch from windowed to fullscreen in the settings but in fullscreen mode the game is still in the windowed mode despite being enabled to fullscreen. And what I mean with the tiny window for windowed mode is that on a 4K monitor (of which I have), the game will run in windowed mode, but any resolution that's not 4K will end up being about a 5 inch wide x 4 inch tall little window. That small window is not a battlefront issue but rather just how any resolution scales on a 4K monitor; which is why I want to get fullscreen so I dont squint whilst playing in windowed. Remember, a laptop GPU is not the greatest gpu so if I increase the size of the window or even borderless window mode to take up my whole monitor, it won't accept my native resolution (4K) and run at a slow 5 fps.
