P3D v2.5 Beta 2 - Terrain Shadows fixed ...

Recommended Posts

My first 4K video ... well sorta, it is 4K but it's just a stop motion (screen captures) showing Terrain Shadows working at various times of day with and without clouds (cloud shadows).

 

 

The is still early Beta 2, more Beta/RCs will probably come later.

 

The bridge extrusion issue is still present on my setup, but I need to do more testing ... have passed on results to LM.

 

Cheers, Rob.

Rob, the Bridge Extrusion issue... is that where I am seeing all the little lines going down from all the bridges and stuff?    Every time I am over a city if there is a bridge or  highway overpass I always see these little grey lines extending down from them into the terrain.  It's very ugly.   Is this what you are referring to?   If so.. man, I hope that gets fixed.

Let me answer for Rob.

 

Yes this is the issue.

Did you notice more fps compared to v2.4?

 

Not really testing for FPS unless I notice something causes a drastic drop ... seems about the same so far.

 

Here is another video I made showing Terrain Shadows.

Thanks for posting these videos. It's intereting to see how things are advancing or being fixed in Prepar3D. From what you've shown, things look real nice.

Hi Rob.

 

Not the same issue, but I asked both here and over at LM about the behavior of the cloud shadows, and never got an official answer about it being looked into. They disappear as one turn around, and come back on again. This happens close to the edges of the screen, and I believe it is more pronounced facing certain headings? Do you have any info regarding this? Not a showstopper by any means, but would look better if resolved :).

 

And thanks for all the updates and stuff

Yes, that's the extrusion bridge scaling issue, and that's going to get fixed in 2.5 too  :Party: 

 

This means 2.5 might be the first update since 2.2 that actually moves the sim forward. This is of course provided they don't break something else with this update.

From what I've read, it's an optimization. They obviously don't want to calculate cloud shadows that won't be visible in the rendered scene. However calculating what's visible and not isn't as straightforward as it might seem. If it buys me a bunch of extra FPS, it's a trade-off I'm willing to make. I guess they could put in an option to calculate all cloud shadows regardless of visibility, at an FPS hit, for those that want perfection.

@JimmiG; Yeah, see that optimization point. That′s what I thought :). An option to render them all would be appreciated. In my case, I can′t see any performance hit whichever cloud shadow option I use (unless I go full on on the quality of shadows of course).

For me that is the worst thing with P3D at this time.

I just renamed to Extrusions.spb to get rid of the bridge issues. Yes, you lose bridges but it's better than having the extrusion issue.

Is that the same issue where you couldn't have terrain shadows and cloud shadows active at the same time? Artifacts flash on screen if they're both active.

... I'll assume its the same issue ;)

Correct issue is now fixed ... but you'll need some serious CPU/GPU power to run both at the same time.  Artifacts that flash on the screen are a direct result of a GPU overheating ... I can induce those vertical artifacts by overclocking my GPU (that includes GPUs that come overclocked).

hi rob, what about the Texture load and blurries? Does it seem better?

I didn't have a problem with it before ... I have not noticed any more or less texture loading resolution issues ... do you notice anything in my videos?

 

If your CPU/GPU can't keep up with resolving texture LOD there are many factors involved:

 

1.  The scenery area being used, for example Orbx Norway is very hard on texture resolving so best to stay with 1024 textures and not overload the GPU with other graphics settings.

 

2.  How well affinity is working with your system (this is trial and error, default Affinity setting works well for my 6/12 core CPU, but others have reported better performance with different settings for different CPUs/environments ... many threads on solutions based on your hardware.

 

3.  How much VRAM you GPU has (P3D will exceed 2GB VRAM easily and in some instances will go above 4GB VRAM usage) ... you definitely do not want to be swapping textures in/out of VRAM.

 

I'm sure LM will keep an eye on performance tuning, they always do.  But for if you're having texture loading issues they can be solved with the ABOVE suggestions.

 

Cheers, Rob.

 

EDIT: combining Terrain Shadows = 80,000m and Cloud Shadows = 80,000m will be VERY hard on your system and if it isn't able to keep up it can produce what folks call "blurries".

Gpu titan . cpu i7 4930k (6cores) 16ram . im rolling on 3 screens but . texture load seem to be a problem on my pc and bluries. texture take time to load and seem to change .

I'm running a 4790K at 4.6 with a vanilla Titan, 16GB 1600 RAM and Samsung 840 EVO SSD. I have the same issues with blurries and texture load time. If I'm descending from 30K and I change to outside views, my textures are blurry. They eventually come into "focus", but they take a long time to begin looking like real terrain.

Texture load and blurries? Does it seem better?

 

FYI, I have reported this to LM ... it's not a big issue for me as the textures will resolve after 2-3 seconds ... but I'll pass the info along.  There are contributing factors to this issue also:

 

1.  How much 3rd party scenery you have loaded (I'm loaded up with Orbx, Vector, airports, etc.)

2.  Texture settings (1024, 2048, 4096)

3.  FIBER_FRAME_TIME_FRACTION, TEXTURE_BANDWIDTH_MULT values in Prepar3d.cfg

 

But either way I have reported to LM.  However, be aware because something is reported to LM does NOT mean it will get fixed.  LM may look into the issue, but if they can't replicate they can't fix ... OR they may be able to replicate, but a fix could break significant amount of 3rd party compatibility, so LM elect to not address it "at this time".

 

To those few individuals in this thread that are offering a "critique" to Beta testers about items not being fixed/reported ... you simply don't know what has been reported to LM by Beta Testers.  In fact, it would appear some have "contacts" that are other Beta Testers and are using the Beta Forum as their ONLY source of information about what issues are being reported ... the Beta Forum IS NOT the only source of reporting issues ... there is Email and LM do have a ticket system.  Whomever is sharing Beta forum information, I hope they have permission to do so ... where appropriate I've got the ok to share information, when not appropriate I'm under the same NDA as everyone else.  

 

Cheers, Rob.

Hi Rob

 

Thanks for the information. Just to clarify, my comment wasn't to critique or badmouth anyone, I just wanted to pass along information that may help resolve an issue in a later release. I appreciate all the hard work and dedication by LM and look forward to future releases. Being a Network Engineer for 15 years myself, I know how trying and difficult it is to pinpoint and resolve issues. Us IT guys are never appreciated. It's a thankless field.

No worries, wasn't directed at you ... just wanted to be clear about some assumptions "a minority few" made about my Beta Testing.  I don't mind critique, but I do mind inaccurate information directed at me.

 

Cheers, Rob.
