Of course, a future fix for performance issues would be getting mostly everything to run on the GPU instead of the CPU...after that...who knows what BeamNG can accomplish ^^ I can only imagine this is way later in the future though.
I hope that'll be a toggle when it happens 0_o I still want the game to run on my laptop! (3.2 GHz Ivy Bridge i5 but integrated graphics)
Getting the physics and everything to run on the GPU instead of the CPU will still be better in your laptop even though it has only integrated graphics and a more powerful CPU. The parallel processing power of a really bad graphics card is still 2x better than of 'any' CPU.
