dscott3984 Posted July 8, 2016 Report Share Posted July 8, 2016 Is this how a thunderstorm is supposed to look? Looks more like a nuke was dropped in the Detroit area... Quote Link to comment Share on other sites More sharing options...
mmerelles Posted July 8, 2016 Report Share Posted July 8, 2016 (edited) In aviation pilots refer to them as -CBs- for Cumulus Nimbus from the meteorology, no pilot under it normal senses will enter there no matter being on a big jet. You round them. They have huge ascending/descending flows than can be thousand ft tall, lot of precipitation, icing, lot of turbulence. They are highly dangerous. http://www.gettyimages.com/detail/photo/cumulus-nimbus-cloud-mojave-desert-royalty-free-image/457995793 you can google images for cumulus nimbus too see more.

dscott3984 Posted July 8, 2016 Author Report Share Posted July 8, 2016 Im pretty familiar with Cumulus clouds. I've never seen a cloud in RW that extends down to the earth in this fashion... Not even microbursts... Quote Link to comment Share on other sites More sharing options...
JohnMAXX Posted July 9, 2016 Report Share Posted July 9, 2016 We've touched on this a million times, our interpretation of -cb- it's obviously one of the most polar topics with SMP... Frank has tried other approaches and settled on this for performance and visual appeal... Important to appriciate that it's actually modeled into the engine for the purpose of similation. 1 Quote Link to comment Share on other sites More sharing options...
frontendrob Posted July 15, 2016 Report Share Posted July 15, 2016 Like them Cumulus Nimbus or not, I want to note that they require too much fillrate in the current version and thus need further optimization. Even on a perfectly running setup that has been tested endlessly for bad weather (= many clouds) situations and stays above 30fps at all time, these clouds, when close and looking straight at them, can bring the framerate down to 20 (or by about 40%). Then picture whats going on when 5 of them are drawn next to each other. Please consider this for future versions, as the "rest" is performing super well and stable (FPS wise) when set to 10km draw area. Quote Link to comment Share on other sites More sharing options...
JohnMAXX Posted July 15, 2016 Report Share Posted July 15, 2016 I dunno, any feature is going to require more resources, be it lens flare or crupuscular rays. If it's hitting your system too hard you might want to think about optimization again. I'm only saying this because I don't see the same issue, yes they do impact but totally doable....

frontendrob Posted July 15, 2016 Report Share Posted July 15, 2016 I might do more testing what exactly happens there, but considering I am running a conservative 10km draw and my 980ti is completely bored with 60% GPU load and 2 Gig's of VRAM to spare during ANY situation considering weather - it's really suspicious these fellas cause this HEAVY hit in terms of frames. Not all the time, but try flying towards one, it will get messy. Quote Link to comment Share on other sites More sharing options...
sundog Posted July 15, 2016 Report Share Posted July 15, 2016 Like you said, the hit is fillrate. So if you're running at a really high resolution, or high anti-aliasing settings, that will exacerbate the impact. MSAA can really slow things down in particular.

Cameron Posted July 17, 2016 Report Share Posted July 17, 2016 Visual appeal? Yep. I like it. Quote Link to comment Share on other sites More sharing options...
sundog Posted July 17, 2016 Report Share Posted July 17, 2016 In all seriousness, I drove past about seven CB clouds the other day that looked just like this here in Florida. People have different expectations of what storms look like based on where they live, and what they've seen in other sims. That said I won't say there isn't room for improvement - there always is, and we're always working on it. Quote Link to comment Share on other sites More sharing options...

mb339 Posted July 19, 2016 Report Share Posted July 19, 2016 Britannic weather encyclopedia "Characteristics of thunderstorm" : Thunderstorm can be many tens of kilometres in diameter with a top that extends to altitudes above 18 km (10 miles). This is thunderstorm? These are thuderstorms! And this is the comparison of a real thunderstorm and Skymaxx thuderstorm: Is this "visual appeal"? Micro-Thuderstom... is visual appeal? Is good? Is real? The simmers do not ask "Pixar Studio thurdestorm graphic"! But at least the correct size to satisfy the visual appeal. 1 Quote Link to comment Share on other sites More sharing options...
sundog Posted July 19, 2016 Report Share Posted July 19, 2016 Our thunderstorms range from 5-7 km in height. Look at the cloud's size relative to the trees it is over, not relative to your plane in the foreground. They are small by cumulonimbus standards but not physically implausible. We need to keep them on the small side in order to guarantee acceptable performance. Quote Link to comment Share on other sites More sharing options...
