Yes, this game has a pretty good physics engine complete with ragdoll physics for your unlucky projectiles.
是的，这款游戏有非常漂亮的物理引擎，为你不幸的发射体完成。
A movement for a physics processing unit (PPU) to accelerate physics engine computations has potentially been diverted by the use of more accessible GPGPUs.
物理处理单元（PPU）向加速物理引擎计算的发展方向有可能会因可用性更好的 GPGPU 的使用而受到影响。

It promises not just new birds and cute little masks for the existing ones, but a revamped physics engine with shifting gravity focused around asteroids and planets rather than one consistent force.

The graphics haven't been completely updated (the cars are basically still just standard polygons), but the UI is cleaner, a physics engine has been added in with power-ups and other goodies, and there is a really robust replay system, which lets players save their best shots and stunts on video, and edit and upload those to YouTube and other video sharing services.
