I'm honestly interested here, why is my statement false?

I really like the Bullet physics engine. I use it everyday in my Blender projects. This couldn't have been better news.

And back to the topic, I honestly think they should find some hybrid between CPU and GPU physics, if only to justify having a fast CPU for gaming.

I mean, my CPU sits between 10 and 20% overall usage for nearly all games. Seriously, it's twiddling its thumbs here (yes I'm probably limited by GPU, but I think that's how it should be!).

I want my GPU to be working 100% at rendering the scene, surely it's more efficient to have the CPU doing everything else? Obviously the idea of a dedicated physics GPU changes this, but the issue with this is that only a very small proportion of users have dedicated cards for physics.

I understand you can compute physics much more efficiently on a GPU than a CPU, but it still seems to me that the developers could get 50%+ improvement in the quality and detail of the physics by calculating on the CPU that they do using something like PhysX. Like, from my point of view, i've got an extra 80% of CPU time to play with that could be rendering great physics!

I love good physics in games, it makes it so much more realistic and the environments much more interactive. I just wish devs would push it more...

Yeah I know, but one can still hope!

At least I know they could make the physics better than it is in games where there is no GPU support. Obviously if you increase the complexity it becomes harder to run, but I think they should still invest more time giving gamers the option to have more complex physics.

For performance reasons I know (for example in Havok) that they cut out a lot of the complexity of the simulation. However, I don't really see physics in most games (not talking PhysX here) as having advanced much from games like Half Life 2.

Cinema 4D now also uses Bullet for its physics
