lights not working - fixed

[Flanders]

Hi

 

I have a weird issue with playing the mod. All lights except for the ambient lights are not working. See attached image. This happens in all the missions I tried today.

The light gem doesn't light up and guards cannot see me if i move closer to a light. If I use the lantern the light gem becomes bright but there is no light in my surroundings from the lantern.

 

So I reinstalled tdm completely and I updated my nvidia geforce drivers but the issue remains unfortunately. Anybody has an idea what causes this?

 

[Flanders]

Update:

If I use r_showlights 1 I see no lights

But if I use r_showlightcount 1 I get a colourful picture with different lights hitting each surface and if I move closer to a lantern post my light gem will light up. This doesn't happen if I set r_showlights to 0 again

That's very weird. Which version of TDM are you running? What are your specs? Does r_useFBO 0 help?

[Flanders]

If I set r_useFBO to 0 the FPS goes down to 1 fps but there is no change in the visuals

So I am playing TDM 2.06 on a windows 7 notebook with latest windows 7 updates. It's an acer aspire 5750G with intel core i5 with 6GB of memory and a NVIDIA geforce GT 520M for which i downloaded the latest updates

Since you have a clean install, deleting darkmod.cfg shouldn't do much, but you might try that anyway. I think another user had similar problem lately, but can't find it.

 

Btw. what's your TDM install path? If possible, make it as simple as you can.

[Flanders]

Ok so I deleted darkmod.cfg and started the game again but the issue remains.

 

My install path is C:\Games\TDM. It was in program files before but I moved it since i had some read-only issues in the program files folder. But both before and after I moved it I had this issue

[peter_spy]

Since you have a notebook, does it use this dual card setup? Like Intel integrated something + nvidia chip? I remember TDM had trouble with detecting my nvidia card sometimes, so I went to nvidia control panel and made a 3d settings profile for TDM, changing OpenGL rendering card option from Automatic to my nvidia card model.

[Flanders]

Yessss that fixed it! I set the 'preferred graphics processor' to 'high performance NVIDIA processor' instead of 'auto-select' and it worked. The lights are back on. Thank you so much.

 

Somehow I did get a deja-vu feeling of some sorts, like I had this or a similar issue before and fiddling in the nvidia control panel fixed the issue... It must have been some time ago since I cannot quite remember what it was exactly.

This does bring to light that TDM engine needs a way to detect the principal GPU better in laptops, based on my search it seems you just use this exports in the engine for that.

extern "c"
{
   __declspec(dllexport) DWORD NvOptimusEnablement = 0x01;
   __declspec(dllexport) DWORD AmdPowerXpressRequestHighPerformance = 0x01; 
}

I suggest filing a feature request.

If you add links, it would be great.

Don't know if I did it correctly (or in the right place) but like you suggested i made a feature proposal in the bugtracker for this.

We have a possible fix for this if anyone is interested

Confirmed that 1) Set "r_useGLSL 0" and restart to revert to old shaders looks to be the easiest solution to fix this issue.

I would not call this a solution but a workaround, you are essentially disabling GLSL and returning to the old and deprecated ARB shaders, so losing the ability to use features implemented in the engine that require GLSL.

 

Of course this does make people, like me, that also add to disable GLSL, able to play the game and that ultimately is what matters but i hope is not a permanent workaround.

You're right. But if it is permanent, maybe it can be included as a setting in the menu for older systems. Or we need new drivers or some such thing if TDM will not support ARB shaders anymore in the future.

Do shadow maps work for you? Do you have access to svn?

No using r_shadows 2 makes them disappear, with r_useGLSL 0 but I assume that is the expected behavior?

 

About svn I don't think so, I have access to the bug tracker tho.

I presume you back-ported this to the 2.07 branch?

 

If you have compiles, upload them to Google drive, Drobox, Yandex, etc

 

and I will put them up on Moddb.

 

Otherwise let me know which source branch to compile.

 

If it's just Trunk then I'll need you to backport to 2.07 since the "cubemap reflect"

change you made in Trunk is not ready for production.

It's trunk

I would have posted it online already but I am waiting for someone with the problem to sign up for testing this.

When they confirm the fix I will merge to 2.07

Please note that these are two separate issues:

1. no lights is missing ext_gpu_shader4 in MESA linux driver - the fix is to send an ifdef from C++ to GLSL.
2. bad lights seems to be GLSL compiler bug in AMD 19.1 driver - work around is to move initialization code around the shader

P.S. great job AMD dropping the ball again. MESA is open source and is entitled to decide on the antique extension support and it actually kicked us in the right direction to add good useful stuff on our side. AMD just enjoys breaking working things and wasting everyone's time.
