I don’t want to go into details, I just did a quick performance comparison between FSX and P3Dv2. Also, this is a comparison on MY computer, MY GPU, the (now) midranged GTX580… I am aware that P3Dv2 works better with faster GPUs, but this test was done to have a comparison grounds for other tests which will have other GPUs, for comparison reasons.
What matter to me is that the first shot is my fully installed FSX, with all bells and whistles, while 2nd shot is the same situation loaded in P3Dv2 (FTXG, mesh and landclass installed, to have same positions, same as in FSX), and autogen set on full. Now, as far as I know, they said there is way more autogen in P3Dv2. Let’s observe…
This is FSX:
Now let me load the same situation in P3Dv2:
Somehow, to my eyes, switching between the two pictures in a full screen, it doesn’t look like more autogen (best save all pictures manually, and then switch between them with arrows, best visible what the differences are). Moreover, the amount seems like the same too.
And, what is needed to retain the FPS we had back in the FSX? Observe:
Now, the same comparison in a bit flatter area, to see the reach of the autogen.
Now comes the P3D, fully autogen:
And all autogen to sparse yet again:
In a conclusion, I can say following:
The P3Dv2 is barely able to maintain the same FPS (first scene yes, 2nd no) as FSX does with full autogen vs sparse autogen. And before some people come with more density, yeah, I can see, further away from the aircraft, there is more density, but in general, autogen distance is the same. Yet, the FPS are 1/3!!! So we are paying with 1/3 of the FPS in P3Dv2, just to have a little bit more of autogen (just compare the shots!) and have it not pop-up? Sorry, too high a price for me. And since autogen is still a CPU thing (we confirmed that in the analysis), it bogs down the system.
And finally, two comparison shots on dense AG and very dense scenery. This is the setting I am running in my original FSX and wanted as a comparison in the P3Dv2. It is very clear that LM put less autogen under the aircraft, and loaded more autogen far away. So however this system is working, does it make sense? And also, why do FPS drop by half???
And before you ask about other settings, I’ve turned off water, shadows, and anything else, just like I did in the analysis testing.
LM needs to seriously undergo the autogen system. I’m not a programmer nor do I really understand what is under the hood, but I see the result. And I am not really happy about it.
What do you think?
