Only if the processing is multi-threaded. I thought I made that point
pretty clear.

Incorrect. The major limiting factor on many games are the CPU. Not
the VPU. Fact and not speculation.

The majority of the work done in games are still CPU-bound.

What did you not understand Sasha? I clearly stated that even single
threaded games are using a multi-threaded model when running on

When a game for example created a DirectSound channel (usually 24+
channels), these are handled under the hood by async threads by the
DirectSound sub-system.

Which is why when you add more sound to a game, it goes slower - CPU
requirements goes up. Thus more CPU capacity can be used to address
the increase in CPU requirements.

And yes, a lot of new game designs are designed around a
multi-threaded model in the core game engine. Look at Flight Simulator
and X-Plane for example.

So you're now saying that your previous statement "While it is true
that here the cpu is usually the bottleneck" is in fact incorrect..?

You are very confusing.. or just plain confused yourself.
