Microsoft.Xna.Framework.Graphics.OutOfVideoMemoryException at ORTS.Viewer3D.PrecipitationPrimitive..ctor (X3186, Marias Pass 3.1, All the Way West)

[John Baldwin]

Just updated to X3186. Running Marias Pass 3.1. This ran successfully on X3148 or so (was a Friday release).

I have tried rebooting: No joy. Log file enclosed.

[John Baldwin (jbnx42)]

Further information: I found that this breaks for me with version X3182. X3181 works ok; X3182 fails as above.

I see that x3182 introduced the new precipitation model and there were discussions on Elvas Tower about running out of memory, so I am afraid that is exactly what happened n my case.

Furthermore I see there was a discussion regarding LAA and non-LAA, so I tried that: LAA fails on my machine; non-LAA *WORKS* on my machine.

Let me know how I can help on this one. I think I can compile source code if you need me to. This coming week will be especially busy, but I will do my best to turn around with answers within 24 hours.

Hope this helps, John

John,

What video card are you using? A previous posted problem indicated that a AMD card was used.

John,

Another post indicated that a viewing distance was set at the max which is 10000 meters and this is with problems. Where is yours currently set at? Try experimenting with the viewing distance to see if this helps clear the problem.

Edward K.

[John Baldwin (jbnx42)]

The viewing distance was set at 2000 (m). That was the setting where the initial error occurred.

The error still occurs at the minimum 500m (can't set lower than this)

Let me know what else I can do for you. Thanks, John

[Edward Keenan (edwardk)]

John,

look for post Out of memory exception under the bug section and post your findings. Under that post, I upload test files that allows for the setting of the precipitation box. Do you already know about those test files?

Edward K.

[Edward Keenan (edwardk)]

The issue on hand is more than likely caused by the fragmentation of unmanaged memory.

[John Baldwin (jbnx42)]

Edward, can you clarify the post you want me to look at? I can't find what you are requesting.
Thanks,
John

[John Baldwin (jbnx42)]

After a bit of searching, dicovered that Edward was refering to a post on Elvas Tower http://www.elvastower.com/forums/index.php?/topic/27035-out-of-memory-exception/

Post number 34 on that thread has modified code based on x3190. Briefly, that code DOES WORK!

Updated to regular x3190: Did not work (same as before)
Overlaid new files from post mentioned above and it did work with default settings.

The full log file is attached. Some new information from that log:
-----
Information: Allocation for 49,999 particles:

      7,999,840 B RAM vertex data
      1,199,976 B RAM index data (temporary)
      7,999,840 B VRAM DynamicVertexBuffer
      1,199,976 B VRAM IndexBuffer
-----
I will try more activities next week. I'll also put a post at the Elvas Tower thread mentioning this.

Thanks,
John

[John Baldwin (jbnx42)]

Changed status to fix committed. This was fixed as of X3192. See the Elvas Tower thread for further info.
