[SOLVED] VideoRam size always to 64 MB [Linux]


Ladro

Recommended Posts

I've seen today on logs that when i launch TDM (on Linux) it says:

 

guessing video ram ( use +set sys_videoRam to force ) ..
guess failed, return default low-end VRAM setting ( 64MB VRAM )
64 MB Video Memory

 

I inserted the value "256" on Doom.cfg on base directory on doom3 and also on darkmod directory, but without any success, it alwasy say this line on launching the game.

 

It's normal, or i can allocate all the ram of my videocard?

 

It's useful to improve some performance, loading time, etc etc?

 

Update:

The error was me :-)

 

Simply I have to run the Linux Launcher *from* the real path (the working directory of darkmod), and not with an absolute path. So *not* like

/home/user/.doom3/darkmod/tdmlauncher.linux +set sys_videoRam 256

 

but with a simple:

 

./tdmlauncher.linux +set sys_videoRam 256

 

from the darkmod directory in shell.

 

Now i have 256 MB of Videoram allocated, the performance is visibile improved (i dont' know how exactly, but it's a couple of fps rendered more and the loading time shorter!)

 

Command:

 tdmlauncher.linux +set sys_videoRam 256

 

terminal support enabled ( use +set in_tty 0 to disabled )
pid: 24899
2016 MB System Memory
====>256 MB Video Memory <====

Have you tried passing "+set sys_videoRam 256" to tdmlauncher?

 

I too noticed yesterday that the console command returns 64Mb for me, but oddly starting TDM reports 512 Mbyte for me.

 

As for the size, if D3 thinks you only have 64Mbyte, it might try to reload textures from main memory to the video ram more often than nec. F.i. if you have a FM which uses 100 Mbyte of textures in one scene, it might load 64, then 36 mbyte into the VRAM, e.g. twice during each frame. But if D3 knows you have more than 100 Mbyte, it will load things only once.

 

How the engine works intenally is not that good know, but I'd set the proper amount of vram. You could benchmark the difference by loading a FM with a complex scene with many textures.

I tried to pass to the launcher from shell the "+seta etc etc" with this:

 

.../.doom3/darkmod/tdmlauncher.linux +set sys_videoRam 256

 

But:

 

...6 warnings
terminal support enabled ( use +set in_tty 0 to disabled )
pid: 24993
2016 MB System Memory
guessing video ram ( use +set sys_videoRam to force ) ..
guess failed, return default low-end VRAM setting ( 64MB VRAM )
64 MB Video Memory...

 

Nothing :-(

 

Update: the problem is present also with Doom3 Vanilla, always only 64 MB of VideoRam :-(

I think it's a Doom3 problem (or min), anyway not TDM.

 

Update 2::laugh:

(see the first message of this htread)

 

Thanks Tels for your collaboration, hope it helps other Linux TDM players :-)

      I've updated the articles for your FMs and your author category at the wiki. Your newer nickname (DeTeEff) now comes first, and the one in parentheses is your older nickname (Fieldmedic). Just to avoid confusing people who played your FMs years ago and remember your older nickname. I've added a wiki article for your latest FM, Who Watches the Watcher?, as part of my current updating efforts. Unless I overlooked something, you have five different FMs so far.

      I've finally managed to log in to The Dark Mod Wiki. I'm back in the saddle and before the holidays start in full, I'll be adding a few new FM articles and doing other updates. Written in Stone is already done.

      You cannot receive PMs. Could you please be so kind and check your mailbox if it is full (or maybe you switched off the function)?

      I like the new frob highlight but it would nice if it was less "flickery" while moving over objects (especially barred metal doors).
