long story short…
I wanted to buy something in the org sale so I bought something which wasnt discounted xEnviro.
Really wanted to have those nice puffy clouds. Unfortunately there was FSE installed already on my XP install (xEnviro isnt compatible with few weather utilities; check the Requirements page at org store)… So I installed second fresh copy of XP, installed xEnviro and begun to test.
First I need to mention that xEnviro has two main sliders which controls rendering of clouds = visual quality :
- static clouds rendering
- dynamic clouds rendering
Both sliders has following steps - Low / Medium / High / Ultra.
Obviously both sliders on Low produce good performing clouds nowhere near the visual quality one would expect.
Both sliders on Ultra produces great looking clouds, everyone can see on the pictures on the web, but can bring your system literally to its knees!
I run XP in 4K and the only acceptable settings were Static rendering on High and Dynamic rendering on Medium. That produced cca 35FPS… BUT, it was on fresh install of XP, default airplane, no updated OSM data, no Ortho, with XP Objects slider at High (or Medium, could not remember now).
Low for Static and Dynamic rendering produced 50-55FPS. Ultra for Static and Dynamic rendering produced 20FPS! Or maybe even lower, 20FPS was all Avitab displayed.
I was depressed! I really wanted those clouds in XP but not for that FPS cost. On Hight settings they looks really good, they dont randomly disappear, they are there even at 16x ground speed acceleration and one can fly around them and they provide great sense of movement! Perfect!
But not perfect on my current system. So I tried to contact org store and kindly asked for refund.
Was lucky and Eliot from org store was very kind and accepted my request even though based on T&C they dont do full refunds. Thanks Eliot!
Closing thoughts - if you have really powerful system go get them, they are (almost) perfect; if you have mid-range system like I have (i7 9700, 2070S, 32GB) think twice…
I ended up buying Ultra Weather XP instead…
