Game Physics

I don't think it is because the computer can not process the collision. If the computer would even struggle, I'm sure it would be made to decrease FPS to have enough time to process it rather than just ignoring the action and letting glitches happen.

The reason these happen a lot more in especially 3D games is because in 3 dimensions there are a lot more to calculate than in 2. In 2 you have the X and Y axises, whereas 3 there's Z as well. That's not just a 50/33 % increase in calculations. It's more like a cube compared to a plane (powered by 3 instead of 2). That's quite a significant increase in calculations, therefore it's very difficult to prevent everything.

Many developers say that by patching one bug, you create 3 more. This can be very accurate. I'm sure these glitches are just minor compared to what Frictional initially had to deal with.

I can imagine these glitches are possible to prevent by editing the engine, but that might even require a complete re-write of the physics engine.
