Updated text as increase my experience as a program. Hello pilots! I confess I was already short of money, but I had to get this addon, wanted to test the novelty of having clouds moving and you go through them. Great job, it was a great idea, practical and beautiful. This will improve the experience of flying. I need to understand the textures, I hope I can change the textures, as well as anyone. The first impression was, this is amazing, look at these moving clouds and reflections. There is one thing better could be the resolution of the texture pattern of the cloud which is only 64 pixels. Therefore, the edges of clouds are unsatisfactory. I thought it had more cumulus clouds, but only with THIS ONE texture resolution. ANYWAY the look is good. On the issue of performance was very good, looks better than the standard, either with HDR OFF / ON in my system had good performance. I liked the Settings menu options. Below are some screenshots comparing the performance. I hope this helps someone. XP-10 Settings SkyMAXX Pro Settings , gives a good possibility to suit most types of machines . Cirrus HDR OFF Cirrus HDR ON 3/8 Cumulus HDR OFF 3/8 Cumulus HDR ON 6/8 HDR OFF 6/8 HDR ON Beautiful Overcast cumulus - greater loss of FPS 37 FPS Good Overcast Stratus - less loss of FPS 100 FPS Good conclusion: Comparing clouds staticas default, the motion feature and turn leaves more living environment with Skymaxx PRO. I am studying and testing the program, I recommend the program yes, and I expect updates and improvements. NOTE : I hope understood my English translated. Thank you Regards , Sabach .
