version 8530 (with its GLProgs)

ShadowMaps problem (not present with Stencil) on a Radeon RX 570 (Catalyst 20.1.3) with NPC ! Shadows are.....partial.

 

 

 

Maybe now that the SVN version is complete (GLProgs) it's time to create a related dedicated thread for betatesters?

Map name? Save game & .cfg download link?

I have seen md5 shadows broken for a while e.g. the bad guy in Closemouthed Shadows.

But for sanity check, I need a specific case to investigate.

I think the problem with shadow geometry models is that

  1. material 'textures/common/shadow' is marked as translucent and
  2. translucent surfaces (e.g. glass and water) are excluded from shadow mapping

I would like to hear opinions on which point is problematic?

Good news guys!

 

1.91.1 OpenAL.lib -> no issue! :)

1.20.1 released if you want to use it in TDM.....the dev has solved a good number of old and new  issues !

Task is not so much to see what no one has yet seen but to think what nobody has yet thought about that which everybody see. - E.S.

Now they seem fixed!

  1. The last parameter here is in nanoseconds, right?
    		result = qglClientWaitSync( bufferLock[frame], GL_SYNC_FLUSH_COMMANDS_BIT, 1000000 );

    That amounts to 1 millisecond? Why so?

  2. At game start this routine gets called twice on frame 0, causing a first sync object to leak.

static void LockGeoBufferSet( int frame ) {

3. What happens on wait timeout? Is it safe to delete the sync object when it has not signaled yet?

4. Any idea why wait always times out on Intel HD 2000 (other than driver bug)?

Hm, I don't remember the context right now, but I think the timeout should probably be longer, more like 1 second. Perhaps I made a mistake with the number, or someone accidentally changed it.

Nothing happens on wait timeout. The docs say it is safe to call glDeleteSync either way.

Try calling glFlush or even glFinish (just as an experiment, definitely don't commit that :D ) right before the wait. It may also be the case that the timeout is simply too short, as mentioned above. If it still times out even with glFinish, it is absolutely a driver bug.

1 millisecond is way tooo small! It should be something like 500 ms, or otherwise there must be some proper handling for timeout 😞

No, wait, this is happening within a loop. So small timeout is fine:

	while ( result != GL_ALREADY_SIGNALED && result != GL_CONDITION_SATISFIED ) {
		result = qglClientWaitSync( bufferLock[frame], GL_SYNC_FLUSH_COMMANDS_BIT, 1000000 );
		if ( result == GL_CONDITION_SATISFIED )	{ 
			backEnd.pc.waitedFor = 'S'; 
		}
		if ( result == GL_WAIT_FAILED ) {
			common->Warning( "glClientWaitSync failed.\n" );
			break;
		}
	}

I think we need to allow a fixed initial buffer size, static data included

Cards with little VRAM (e.g. 1GB) tend to end up with the VBO in the system RAM because it the VRAM is already filled with textures at the time of resize

I believe there are cvars for that.

Also, static data is now stored in a separate VBO again: 5598

      Happy birthday to me!
      Yes, today's my birthday and as much as I want to play The Dark Mod, I won't until it's late Autumn, where it should be a bit chilly in my place and there's some wind too.
      For now, it's time to enjoy my birthday, if any of you want to play a great fan mission in my honour...Well that's asking too much, just play the mission because it's fun, not because of me, enjoy it yourself! 💪

      Took a break from TDM until I got my backlog under control. It's been months and it's still not "under control". Damnit.

      I sleep well at night knowing the player will never see the absolute nightmare that is my sealing brushwork outside the playable area. Only the pointfile can judge me now.

      Somehow I admire the fact that the material from Dune has now been filmed for the third time. Personally, I could never do much with the material, but as a child of the 80s, I of course know the David Lynch movie...and that movie was at least funny!
