Ati 5750 memory missing

fourbe

<div class="IPBDescription">only 256Mb in NS2</div>hello all

I playing NS2 in very low detail because the game don't load textures on all memory of my ATI 5750 (512mb).

my computer :
- i5 3550k (3.3ghz)
- 8Gb DDR3
- mobo gigabyte Z77-D3H
- graphic Sapphire ATI 5750 512MB
- power 750W

all is new except graphic.

The screenshot :
[attachment=36147:ns2.jpg]

143 + 31 +78 = 252 Mb
When the "256Mb" memory is full, game use RAM (approximately 150MB on 4096MB)

I'm running Skyrim with good textures mode !

thx for helping

(bad english, cause I'm french :D )

up?

win 7?

try disabling aero

Not sure the detail, but it looks like other stuff take up roughly 250-260MB of vram (my 6950's total is 1796 out of 2048MB vram). However, you could benefit from a video card upgrade (such as going for a well priced <a href="http://www.videocardbenchmark.net/gpu.php?gpu=GeForce+GTX+560&id=71" target="_blank">GTX 560</a>). It pains me to see a 6 month old CPU paired with a 3 year old GPU.

- same problem without aero.

- I don't buy a new GPU because it's very expensive (GTX560 - 240€/310$).

trying to running ns2 with GPU-Z Logging : 247MB VRAM used
running Skyrim with GPU-Z logging : 492MB Vram used !!!!!

You're on windows 7 64 bit yes?

Texture Streaming on?

For NS2 there is nothing wrong with that 5800 series, apart from the low memory (512Mb). I run a HD5870 variant with 1Gb VRAM, which is of course more powerful. It's slapped together with a 2500k @ 4.2Ghz, but NS2 isn't exactly known for it's GPU hogging


Also with texture Streaming set to on, you will never use all of that 512Mb VRAM. it basically hovers around 100-200Mb and should be used for that amount of VRAM for older rigs. 512Mb is also at the lower limit of running NS2. And without texture streaming, it will use ~500-600Mb on Low texture quality. Not using texture streaming on just 512Mb, will start swapping textures/materials between RAM and VRAM, which can cause hitching on older CPUs+MEM (not a problem for you btw :P)


--Still a bit odd it shows less than your total available (free) VRAM though...

Ok, I need a new graphic card :/
