Unforunately, I had to remove my review on performance comparison.
I made a mistake in the review, something I really don’t do often, and this time the error was so deep, I didn’t have a chance of noticing it, only suspected it.
What happened: I had Windows 7 installed with full FSX, everything I was using for a long time and flying.
Apparently this installation was broken – it yielded way less FPS than FSX is capable of. I had no comparison to run!
So after I have seen such high FPS in P3D, I believed that FPS are higher in P3D in general.
I reinstalled W7, put P3D on it, which had the same performance as my old FSX under old OS-installation.
It was not an OS fault. It was simply bogged down FSX, which ran slower.
Couple of days after I did the test, I got suspicious after some have reported same speeds, so I installed FSX – and hold and behold, I had similar FPS in FSX.
After not being able to believe how stupid the whole thing went, I cleaned up the machine ONCE again, ran both FSX and P3D setups, in the clean environment I ran the tests and came to a simple conclusion: P3D yields the same FPS or a bit better FPS in some scenarios.
It is a bit smoother though. But if you are heavy armed with my tweaks under FSX, you can also come very close to the smoothness in P3D.
Nevertheless, P3D is not bad, it is the way forward, it already offers features that FSX doesn’t offer (sound on lost focus for instance…), and it’s going only to get better.
Yet again, I am very very sorry for what happened, I stand by my mistakes and I hope such error will never happen again!
