spring 95 + BA 7.84 and video memory

[Silentwings]

As far as I know, in most cases this is connected to lua memory usage and its only a few cases where it isnt. So I suspect more than one bug here.

Neonstorm there is if you have a semi recent NVIDIA gpu use

watch nvidia-smi

For me and my 9800gfx I just get basic usage but iirc more recent gpu get a more detailed output

I tryed to use gDebugger but it crashes on start for me. Even amd version of gdebugger had the same crash.

But actually Beherith helped me
He suggested to set these options:
AllowDeferredMapRendering = 0
AllowDeferredModelRendering = 0

and I got -200mb to video memory usage (like 700mb with antialiasing set to 4 + enabled LuaShaders support + Bump Mapped water etc). That works for me!

Only BAR uses these features. So I will enable them when I will decide to play BAR or when I will buy better Video card.

Thanks Beherith!

That is still kind of odd; I am playing with a 560 Ti on Kubuntu and I have no troubles playing at max settings including all deferred rendering enabled.

The amount of GPU memory used by AllowDeferred*Rendering largely depends on screen resolution. If both are enabled, the total footprint in bytes minus driver overhead is 2 * (6 * sx * sy * 4) which yields 80MB at 1680x1050.

A "Dell U2713H" monitor has a native resolution of 2560x1440, so the raw footprint there would be 168MB when running Spring in fullscreen mode. Subtracting that and other known vidmem consumers still leaves a rather large chunk unaccounted for.
