Why does clouds crush your system! Its the only thing i'm struggling on.

I use just 3 layers, looks good and doesn't impact FPS.

Are you referring to cloud layers in ASN ?

Almost no impact to frames with Opus and Soft Clouds.

Whats the difference with soft clouds and REX4D? I'm using the latter

Soft clouds are far better,there just what they say on the tin.

 

When people say clouds hit fps that's normally because there using Inspector for AA a big NO unless you have a 980+

 

I have ASN at 5 levels better overcast etc and with 780 6gb have no problems with fps.

I don't use NVCP or inspector. Only set prefer maximum performance.

REX4 is capable of installing 4096px cloud textures which will impact FPS a lot in heavy cloud cover. As near as I know Soft Clouds are limited to 512px so if you have "Low level clouds" set to 4096 (Ultra High resolution) in REX4's main configuration page you'll likely see a big performance difference when you install a soft clouds set. If you have 512 (low resolution) selected you won't see any difference at all performance-wise. I personally think high res cloud textures are overkill, I resize mine to 256px manually, they look fine. The default P3D3 low level cloud texture is 256px incidentally.

Bit pointless having softclouds if you have REX4D as you can set 512 res clouds

Staring at a computer monitor for hours at a time pretending to be flying an airplane is a bit pointless too but we still do it, lol.

I don't own them but Soft clouds (obviously, I'd say) aren't simply low res versions of existing clouds...

Soft clouds look great and almost no impact on FPS.

The point is Soft clouds look a lot better than there normal REX4D clouds and installed at 512 have no hit.

There not some low res version there imo the best clouds out there.

 

Win win.

far from pointless  :smile:

So does soft clouds have a less impact than REX4D?

By pointless i mean, if REX4D produce 512 low res clouds why buy soft clouds? Sorry but am i missing something here?

Yes, you are missing something. It's not about the resolution at all. Soft clouds offer 'volumetric-like' soft looking clouds so they are and look different (and according to some more real). They are simply not REX4 clouds in low res. Most people who own REX also bought Soft clouds so that shows there is a difference. (Why soft clouds had to be a seperate product and not simply an update for REX is another story...)

My problem with soft clouds is that they look out of place in the summer.

 

They look like heavily glaciated winter clouds.

See below for a comparison of the top level MIPs from one of the standard REX 4 TD 512 cloud layer texture sets and a soft cloud set. It appears to me that the soft cloud sets are images that have been processed with some type of blur filter in order to make the transition from one "layer" to the next more seamless. FSX and P3d use multiple layers (these layers are actually vertical planes) to achieve what is termed 2.5D volumetric clouds. Note that the sim default texture MIP is 256.

 

The blurring makes for more a fuzzier transition, which is quite accurate for older, decaying clouds, where much of the condensate has evaporated.

However, it's inaccurate for younger clouds where evaporation has not begun to set in heavily, and the transitions are sharp and sudden. Such as the one below, before we penetrated its updraft a few minutes later.

Quick question.  Do you turn on REX's HDR setting?  Is there even a point in using it since P3D has it's own HDR sliders?
