Terrain Issues

[grant977]

I have been having an issue for nearly a year now with Nevada. I have to load it twice or plan and or terrain textures load slowly or not at all. When I’m flying around especially as I fly further away from my starting point usually Nellis the ground becomes just ocean then suddenly it loads the textures.

 

When I go in and out of f10 map the terrain is blurry again. I do not have any fram rate issues very smoot running with slight stutters when terrain loads or first explosion happens.

 

I do not seem to get the missing ground when in Normandy, It does happen to a lesser extent in Georgia.

 

Using time compression worsens the missing ground issue.

 

When I can I will post screen shot and system specs.

 

Thank you.

Post the specs, but I suppose your gfx card might not quite cut it. Nevada map has always been the most demanding RAM & VRAM-wise, being almost four times bigger (file size) than Normandy and more than twice bigger than new Caucasus.

I think that might just cut it to shreds ;)

Hmm then what’s causing my issues with Nevada?

Anyone see a bottleneck?

Hi, I got a very similar system and Nevada runs super smooth on my box.

You have not written about your hard drive you are using.

Is it an M2 drive? Have you installed the appropriate NVMe driver?

Is it DCS 2.5 OB you got installed?

 

Since you got the same ridiculous amount of RAM like I do, try to load all Nevada terrain files into memory first to see if this changes anything:

 

Open Task Manager --> Performance Tab --> Open Resource Monitor --> Memory Tab

Check the Standby Memory: mine is 6032MB after boot

 

Open a “Windows PowerShell” and do the following:

cd “C:\Program Files\Eagle Dynamics\DCS World OpenBeta\Mods\terrains”

get-childitem -recurse Nevada | select-string a | out-null

 

While this command runs, check in: Task Manager --> Performance Tab --> Disk 0 ©

How many Megabytes per second do you get there? I get between 18 and 23MB/s most of the time.

 

Let the above command complete, mine took about 30 minutes.

Once complete, check the memory tab again. Your Standby Memory should have risen by about 34GB. Mine was 40655MB after.

 

Now start DCS and fly in Nevada. Since all files are now in RAM, in theory, it should mask any hard drive bottlenecks. But then, I do not know if my trick works, it is just a thought I had, but if it works, then there you go, you got a problem with your hard drive or driver.

I tried you fix but getting a lot of red lettered errors when I do.

Hey there… what I posted is not a fix! It is just a test to see if it could be your hard drive.

 

 

You got red errors because you blindly copy/pasted my commands. What I posted is the default path. It seems you got DCS installed on another drive, so adjust the path according to your environment.

 

 

Your SSD is perfect, as is the rest of the hardware specs you posted. You should not have any problem running DCS on this hardware.

 

 

Here is what I would do:

 

• Run my test just to see how it goes. (I am interested myself)
  
• Check if your Saved Games folder is also on an SSD
  
• Update Windows
  
• Update all your hardware drivers
  
• Repair DCS

One more Thing:

 

• Delete the metashaders and fxo directories in your Saved Games folder: C:\Users\yourusername\Saved Games\DCS.openbeta

No joy. Even did a clean install and still have the disappearing terrain issues on Nevada.

Frame rates are not an issue the damn terrain taking forever to load. Also forgot to mention above the F10 map takes forever to full load as well.

Also how do I get it to load all of the terrain?

I have just noticed something myself. When I quickly go into the F10 map and then go back into the cockpit most of the texture is missing and it takes several seconds to come back. This effect seems kind of stronger the more you zoom out in the F10 map. This only happens to landscape, over Vegas, I did only notice it in the far distance.

 

This might be what you are seeing but you might have another problem that exaggerates this.

 

Does anyone else see this happening??

 

Tested it in Spitfire free flight instant action.

Got a GTX1080, 5.6GB of 8GB used, 64GB RAM, resolution 3840x2160,

Snap I get the same issue as well when I go into F10 map.
