Beta Test / Technical

[rgleason]

In Nvidia Control Panel > 3D Settings > Set PhysX Configuration >
Select a PhysX processor: Choices are Geforce GT 540M, AutoSelect and CPU. I am setting it on CPU and will see what happens...

Seems to still load the Nvidia Geforce 540M.


The final try to turn off Nvidia hardware opengl was to use the separate applications settings, under "Manage 3D Settings" > Program Settings Tab > Add Opencpn.exe for 4.8.0 > then turn stuff off. First time I tried turning everything off and the Nvidia program stalled...

Then tried setting CUDA-GPU > None. It seemed to work, but the Nvidia was still loaded as shown by the log file.

So I am stopping this test as I have run out of things to try. Sorry Did-g, I'd like to test it!

[rgleason]

BTW
In Nvidia program "Restore" factory default settings Globally for all programs, caused OpenCPN to choke and result in lockout and a memory use error. By changing Ambiient Occlusion Off, Anisotropic filtering to x8, Antialiasing FXAA to Off, Antialising Mode to Off, Opencpn started running as expected.

I don't know exactly which one fixed it, but I think one of those changes made a difference.

Hi,

Could be that system opengl32 dll is already loaded by another software.
I've tested on W7 et W10 with low end Intel graphic and CPU, seems to work fine.

Doing the Qt way doesn't seem too hard but you have to change and recompile Wx a little.

I managed to build opencpn with appveyor from a github repo, sort off, but it won't cut it for that kind of work.

I've read how to compile O on Windows and, well is Windows dev that bad? After downloading gigabytes of stuff free 'community' C++ compiler claims it expired and so on, I'm too old for that kind of BS, won't do it.

Is compiling with mingw still working?

BTW what is your workflow with weatherfax, radio or Internet download?

[rgleason]

did-g,
I can compile Opencpn and PI for windows. PI as standalone and integrated.
I am using TDan's BatchUtil for Opencpn compiling. I use Visual Studio, did try mingw with Sean years ago. Did setup and have Linux in VirtualBox for a while.

Are you suggesting to compile a special version that uses the opengl32.dll?
How would I get that driver included in the code?
I did some programming in College and Pascal (procedural) for Architectural CAD Macros, but C++ is another world.
Could you talk me through the necessary additions/changes for that?

Then I will do it. Best.

Hi,

Last time I did work on windows was 20 years ago but in my understanding if an opengl32.dll is already loaded windows dynamic loader will use it when starting opencpn, if not it will look at dll in various places one being the opencpn.exe directory.
cf:
https://msdn.microsoft.com/en-us/lib...(v=vs.85).aspx

https://msdn.microsoft.com/en-us/lib...(v=vs.85).aspx

and so on.


If we want to be able to always load our own opengl dll we have to do it manually by:
1) not using opengl32.dll name

2) not linking against opengl library when compiling opencpn, this one mean we can't use stock wxWidget (it's linking with opengl for us).

3) at run time either load windows opengl32.dll or our OCPN_opengl.dll.

Point 2) is an issue, ideally it should be backport in wxWidget.

On the other hand maybe there's some way to do it like on unix ie:
LD_PRELOAD=./libopengl.so ./opencpn

On msdn they wrote about manifest, side by side, whatever
cf:
https://msdn.microsoft.com/en-us/lib...(v=vs.85).aspx

BTW what's in your :
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Session Manager\KnownDLLs

[rgleason]

Did-g
1. I don't find ocpn_opengl32.dll in the OpenCPN 4.8.0 directory & subs.
2. KnownDLL's is attached below.

Thank you for fixing some of the leaks in wxfax!

I am thinking that I would possibly need to compile a special version of opencpn with the software opengl32.dll, so I looked to try to understand how it works. The only file I could find was in C:\Users\Rick\Documents\GitHub\OpenCPN\buildwin ocpn_gltest1.exe which just tests opengl capability.

If someone who programs for windows can tell me what to do, I'd be glad to test did-g's opengl32.dll but at the moment it is not loading.

[hoolie]

I followed did-g's instructions and the software ran right away in Windows 10, as I reported in my post #2027.

Here is an extract from my log file:-

12:41:15 PM: Creating glChartCanvas
12:41:15 PM: Metrics: m_display_size_mm: 304 wxDisplaySize: 1280:800

12:41:15 PM: OpenGL-> Minimum cartographic line width: 1.0
12:41:15 PM: OpenGL-> Minimum symbol line width: 1.0

It shows that opengl32.dll did indeed load and run.

Again, as reported there wasn't much difference in performance either way.

[rgleason]

Hoolie,
Thanks. I followed the instructions and it did not work. Your confirmation and log drove that home. Guess there's nothing more to try.

Intel HD 3000 drivers support OpenGL 3.1 (from Intel website)

I will change over to using my Nvidia Geforce Adapter which is faster and see if this is a feature selection in their software.

This is in order to use Did-g's opengl32.dll Software OpenGL with OpenCPN 4.8.0.

Anyone have any ideas how to do this?

I've really been struggling with my Intel HD 3000 card on Windows 10 X64. I came across this thread and it lead me to try a few things. In the end, I actually found a OpenGL.dll (software OpenGL) that was built for an old game. I downloaded that dll and put it in the OpenCPN directory. After that, I was able to use openCPN with OpenGL turned on (however texture cache doesn't work).

OpenCPN is now at least usable at about 15 frames per second using CM93 charts. May be worth a try for anyone with older Intel HD cards. Here is the download link to the DLL.

Hi,

What is your screen resolution?
What plugins are you using (radar overlay)?

Thanks

[did-g]

setlocale is a dangerous function.
it's global but internally opencpn is expecting LC_NUMERIC with '.' first image is a VDR replay (via network not VDR plugin).

second is the same replay after a plugin used setlocale.

Boat on screen and track are off by up to one nautical (mixed up between ',' and '.')

We must do something.

For info:
I've Intel HD 3000 card on Windows 10 X64 wo any significant problem these days. I use the radar_pi a lot. What I did after Win10 upgrade, from W7, was to change to a video card driver from W7 (or 8, don't remember) and locked the update for that driver.
I've a Intel driver 9.17.10.4459 from 2016-05-19.

I will source that exact driver and try it out. At this point I have tried about 4 versions of the driver and they all have the same result. My frame rate is about 1 frame every 5 seconds (no not kidding). The only way I have been able to get OpenGL to work is with the dll I listed above..

However.. I will source this driver version and test it out. I will report back..

And I don't use "Show FPS". It says 275 but everything is slower when checked.
