Quote: its really strange that some get a speed increas while some dont. how can that be?
I think this is because many people are still running the old version of gamestudio. The new one (6.5) was only announced as public beta on the forum, not as an official release (although the news page does mention it, most people only check the forums).. The new version is remarkably faster than the old one, but A7 is (on my systems, both old and new) not much faster than 6.5.
Franks explanation could also be (part of) the reason. Although rendering never happens on the CPU, culling does.
Quote: old systems with weaker CPU and decent GPU render with A6 mainly on CPU.
In A7, there is less work for the CPU (no BSP-tree culling, optimizations), thus removing the bottleneck or moving it to the GPU.
