I was three of those pilots if you're counting Nexxxeh* separately.
This is on Win8.1x64 Pro, X4 640, 6GB DDR3, nVidia GTX 960 2GB (Driver 361.43 at 1920x1200, 59Hz). Mech NKRO keyboard (CM QF TK, UK layout, blue switches), Logitech RX1500 mouse running straight on the desk.
Nexxxeh was my initial run with Firefox 42.0.4. It was cut short because there were weird black diagonal chunks sliding down the carrier/drop ships. It was like moire, just really thick. Firefox does have the latest version of uBlock Origin loaded.
I didn't faff about at the time, as I'd missed a couple of playtests and was eager to make the most of the half hour. Sorry! You're welcome to contact me via my forum email address if I can help get to the bottom of that.
I then switched to Opera, which was awesome.
I initially (NexxxehOpera) tried using the mouse, but still couldn't fly and shoot worth a damn. Switched to keyboard mode and could fly and shoot and was vastly more successful. Very much miss having strafe available in Keyboard mode though. I've got an NKRO keyboard.
I somehow managed to trigger a "back" in the browser, which kicked me out, so reconnected at NexxxehOpera2. I decided to try JUST using the mouse, and dropped my throttle to minimum and just became a floating gun. Struggled to kill anything, but did rack up a good number of assists.
Again, had a blast. I appreciate it's not stuff you're focusing on, but an auto-centering reticle, strafe in keyboard mode, and a brief howto might make it quite easier.
Cheers, catch you in a month!
