Rex4 Clouds very bad perfomance.

and maximum cloud draw distance

 

Why not then limit cloud draw distance to 80?

I keep my Min and Max draw distance the same so ASN doesn't have to make adjustments on the fly.   Human eye cannot make out much detail beyond 65-70 miles iRL.   And I actually got my numbers reversed.   I set cloud min/max draw distance to 73 and maximum visible distance to 70.  This prevents me from perceiving any cloud pop ups at the extreme vision range.

Definitely something wrong.    I am telling you though, don't go over 1024 resolution textures and also set your draw distance to a realistic human eye seeing level.   I run my ASN with 70 mile minimum and maximum cloud draw distance, 5 layers total, with visibility set to 15 miles max on the surface and 73 miles at altitude.   This is what the human eye is capable of in real life in most conditions.   The realism, to me, goes up big time with the look of the simulation outside my cockpit.  It feels more real to me and less like a computer simulator, not to mention the huge boost I get with rendering because all that terrain and autogen is being hidden in the haze layer.

 

OK, msg received.  I tried to reply to your post point by point, but this venue apparently can't handle that, so it'll be one statement.  Based on your advice, resolution and draw distances need to be substantially limited. 

 

So be it, if that's what it takes for Rex to perform acceptably.  As far as being "more real to me", and not like a computer, that's the crucial issue, far as I'm concerned.  My goal is to make the sim as much like it is in "real life", and I DO have a frame of reference - I have more than 2,000 hrs of licensed, logged real piloting time, and I know exactly what it "looks like" up there.  So, the issue is, trying to fiddle with the "settings" to try to re-create what I expect, based on that flying experience. 

 

Sometimes, I think the real flying is easier than the computer flying - at least, one doesn't need to mess with resolutions and draw distances. B)

There has to be something more going on here i think, I have my textures in all layers set to 1024 resolution and have ASN cloud layers at 20 the highest setting and also, REX 4 HD isn't just the problem racklefratz there has to be a setting causing it, I paid $2800 for a new system 2 months ago and i am running REX 4 HD, ASN, FTX Au Regions, FTX Au Airports, Ultimate traffic 2 and have all my sliders set to FTX recommended settings and flying the PMDG 737 NGX and i dont see below 25FPS the min i will get down too even at a add on airport is 20fps

 

I have Steve DX 10 fixer installed was the lucky one to purchase it and did alot of hours and test flying with changing the FSX.CFG and Nvidia inspector settings and the performance im getting is amazing

A bit off topic - (my post. not yours) but thanks for posting that info because I plan on building almost the exact same build in a few months

So cloud draw distance is limited to a value or is it maxed at 250?

Cloud draw distance is limited to the same minimum distance.    So set your minimum to 73 and your maximum to 73 in your ASN settings then so your max 'visual' distance to 15-20 miles max on the surface and 70 miles in the area in your ASN settings.   Fly it.  See if you like the look of it and see if it helps get you a few frames back.  It does for me and looks far more realistic than 250 mile draw distances or even 150.

lol.   I bet it is just a little more expensive, just a little more, not much more, than simulated flight.    Just fiddle with the draw distances until it gets to what 'you' think looks right but default settings, in my opinion, are way to optimistic if you are going for a more 'realistic' look.   The human eye just can't see that far.

Was also getting bad performance but changed ASN to FXGlobal and that made all the difference (simple wx interface, no pop ins, very steady).

I have all REX clouds at 512. And NO TEXTURES in FSX sim over 1024 (even airport adds). DX9.

Make sure you have REX SP2 and the new updated Texture set.

I now use "SimStarter" for startup profiles-freeware). IMHO a Game changer!

I was using REX4 - Texture Direct and had my texture compression settings set to 32 bit. I was running ASN in California and there was almost total cloud cover. My fps went to 5, 8, 1, and then I shut it down and changed the settings back to DXT5 for the clouds and DXT1 for the waves and back to 30 plus fps again. I also made sure my low/high level clouds were at 512. I have my Texture_Max_Load set to 2048 and I honestly saw some decent clouds with the 512. I may try it at 1024. I haven't been in the single digits since I built my current Haswell i7 4770K w/780GTX video card.

Sounds like even the latest system will perhaps still give problems with settings close to max eh Jim?

It's that old FSX 2006 platform!

I noticed that ASN also eats a lot of system resources. Same with Opus, so I found that FS Global was just perfect. I can fly in full IFR bad weather into LAX (no pop-ins) with REX4, NE CA lights and Aerosoft LA and still get 20 FPS smoothly.

DXT5 and DXT1 only. Texture Max Load 1024, 512 clouds, smooth as silk now!
