skelooth Yep, I've done that! And not only with tails of 5-10 pixels, much more to be sure : )
It doesn't have any negative effect when the projectiles come from the player, but enlarging the hitboxes for the enemies weapons makes the game much harder, of course.
megatronx Only cutscenes runs on high quality, all the "real" game runs in low quality already to max the perfs. It feels like a 720p only game, but with some "sharpen" photoshop effects on the GUI, it looks pretty ok even for graphic nazis.
That said, instead of asking to the player to change his graphic settings if the game drops under 45fps, I could autoswitch like you do, and then bring back the high settings if the game runs smoothly for a long enough time.
That's a very good idea, thank you!
Note: I feel like I'm hijacking the thread, I'll now shut up for a bit and let sqiddster and Ashley continue ; )
