spring 95 + BA 7.84 and video memory

[jamerlan]

Hi to all!

I am playing on near on low settings and memory of my Nvidia card is full.

If I close spring - 300 of 1000mb is used. If I play BA (for example on tabula v4 map) - my video memory is full. When it's full - I have FPS frop and pauses during the game.



So I lowered video settings and turned on "texture compression".

95 Spring uses more video memory? Or it's just my new monitor and I need a new video card?

My resolution is: 2560x1440

This seems wrong. I have only 256MB and no problem. Also the PCe usage looks like you are swapping or something.

System... Linux? If it's Linux, then maybe it's your DE not rendering directly.

[jamerlan]

Just tested. On lowest with compression I have 800mb used on DSD

Yes, I think it's garbage collector running on GPU (trying to find free memory).

Yes linux. Fedora 20. On fedora 19 I saw the same behaviour.

Check if it still happens after issuing /luaui disable.

In the case that stops the leak, find out which widget(s) are responsible for triggering it: start with the top half of all widgets enabled and the bottom half disabled, run nvidia-settings to see whether it still leaks and if so split the top half into an enabled / disabled part, etc. Then we can derive which Spring function(s) are involved.

Otherwise, you may have to use an OpenGL debugger tool.

Thank you Kloot! I will try to disable widgets and monitor video memory.

I am noob in opengl. Just for fun I did: ./apitrace trace --api gl /home/revenant/.spring/engine/95.0/spring

these errors I got:
apitrace: warning: unknown function "glVDPAUFiniNV"

I have the same card, but on windows, here is my gpu load when looking at a /give all on BA tabula v4:

New BAR unit code name "borg cube" detected in top left corner of minimap.

[jamerlan]

I am playing in windowed mode too.

With texture compression ON and almost on lowest settings(without shadows etc) I have ~ 800mb used too just after start with /give all Even with /luaui disabled
just like Beherith. And this is just a game start.

Just after start and without units I have ~700mb used on tabula 4


I don't think that this is wrong. Maybe for this resolution I just need better video card.

Yer gfx card will be assimilated

[Beherith]

Same rez as you, jamerlan. Does disabling texture compression even have any effect for you?

Dansan, this is a BA screenie

Looks like NOT :-D

If I enable "LuaShaders support" - I see +100mb memory usage (900+ in total).

So: No LuaShaders, only basic water, no shadows, no 3d trees, no hi-res clouds etc for me with this card

[NeonStorm]

Is it possible to write some code stuff which checks what is allocating all the memory?

something like /debug memory/cpu usage?

It should upload stats like widget x has %x total mem/cpu usage - compared to/against a set of other widgets - after start, /give all, etc, collecting (player-names[min..max], avg-min, avg-max) for each major version and test situation.
+Some script to test new mod+spring combos after download.

It would give registered devs a message, if their widgets start to work worse for some players.
It would players give a clue what works wrong - without the need to test everything manually.

with, and without spring 95.0, 1920x1200/32bit (windowed), stock widgets plus a few extras

[jamerlan]

dansan, which desktop environment you use?
I am on gnome 3.10

Do you have "LuaShaders support" enabled? Shadows? Water effects?

[Beherith]

I run with all the bells and whistles pretty much maxed. Except anti aliasing, that eats a lot of gpu ram.

[dansan]

XFCE 4.10 without compositing (no 3D desktop)

LuaShaders "enabled", Shadows "disabled", Water quality "basic", Compress textures "on", Draw smooth points "on", Draw smooth lines "on", full-scene AA samples = 1.

[NeonStorm]

Spring 95 eats 3GB of my ram too - Is it memory leaking?

Does somebody know a good tool to get stats on video memory with Arch linux via command line?

[Beherith]

Neon, it would be most excellent if you could test the replay of a game that produces so much ram use, and see if it can be reproduced. Maybe a valgrind run is in order if it can be reproduced.

[Silentwings]

I'm not able to test it myself right now - but if no one has done the bisection test that kloot suggested above, imo that should be the first thing to do.

[Beherith]

silentwings, the easy test of /luaui disable did not prevent excessive memory use for him. jamerlan, would you be willing to test with an opengl debugger?
