TechPowerUp GPU-Z 0.3.7 Released
TechPowerUp released the newest version of GPU-Z, our graphics subsystem information and monitoring utility. Version 0.3.7 brings with it some significant feature-set updates that enhance usability, and add the the vast amount of information this tiny utility can display. To begin with, GPU-Z now shows the GPU Computing features your graphics cards support, including whether they support technologies such as DirectCompute, OpenCL, CUDA, and PhysX acceleration. Building on the infotips feature the previous version came with, the Sensors tab now includes handy infotips too. For NVIDIA users, GPU-Z is able to display the exact amount of video memory in use by making use of a new driver-level feature by the company.
GPU-Z also includes full-support for ATI Radeon HD 5970, NVIDIA GeForce GT 240, and improved support for Intel G41. Detection features have also been added that help determine counterfeit graphics cards that use some old GPUs relabeled as new current-gen GPUs. Several other stability issues have been addressed. GPU-Z is backed by our extensive video-card BIOS database, and overclocking validation system.DOWNLOAD: TechPowerUp GPU-Z 0.3.7
A complete list of changes according to the change log is as follows:

also I have a GTX260 1792MB fired up GTA IV all settings max out but the memory usage under GPU-Z states it is only around 800MB? supposed to be around 1.5GB as you can see on my PS. Well I only played for about 5 mins just running around bumping cars and people.
guess gta iv programmers overestimated their resource usage. the readings are provided by the nvidia driver, i trust them more than what gta shows
I have set the memory usage to max memory usage after I exit GTA IV
will try to play GTA IV for 30 to 1 hr to see if it increase mem usage
EDIT:
ran GTA IV benchmark here's what I got:
Statistics
Average FPS: 52.91
Duration: 37.21 sec
CPU Usage: 76%
System memory usage: 68%
Video memory usage: 63%
Graphics Settings
Video Mode: 1680 x 1050 (60 Hz)
Texture Quality: High
Texture Filter Quality: Highest
View Distance: 100
Detail Distance: 100
Hardware
Microsoft® Windows Vista" Ultimate
Service Pack 2
Video Adapter: NVIDIA GeForce GTX 260
Video Driver version: 195.55
Audio Adapter: Speakers (SoundMAX Integrated Digital HD Audio)
Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40GHz
File ID: Benchmark.cli
Video memory usage: 63%
so around 1111mb out of 1764mb (the 1764 is shown under GTA IV graphics settings) of video memory usage
GPU-Z showed around 780+ opening firefox added some video memory usage to 810mb of video memory usage
got back from playing GTA IV so this time with lots of explosions, exploding cars, gun shots. the max video memory usage was 975mb.
I guess the graphics settings you set in GTA IV which also indicates the needed vram is your MAX needed vram, so mine should top around 1.5GB of video mem usage.
edit: when directx tells you your device is reset you: allocate memory for texture/model, load texture from file, tell directx to send it to the gpu, release memory. repeat.
directx _may_ keep a copy in main memory if it thinks it's wise to do so but will release it when it thinks it's wise to do so again. you can avoid this by passing a flag to directx ("unmanaged" textures)
of course you can be an idiot programmer and keep a copy of your stuff in main memory, but if you do that microsoft should get a restraining order against you for their developer tools.
So using the ATI cards as an example, and I do apologize if this has been remarked elsewhere, by taking the card info from the DXDIAG it sounds as if the tool then populates the rest of the information using some kind of HW ID via the driver itself and/or the BIOS of the card itself. I mean, it's the only way I could think of that it would be possible to get such detailed information down to the GPU core which I never thought was even stored anywhere in the driver itself but I'm just a h/w junkie so I could be wrong. :)
I guess that pretty much means that unless AMD changes the actual driver to reflect the name of the card itself there is not any way to implement the correct info via this tool? But if there is a way to do this I have a lot of these cards and I'd be willing to use the lil "dump BIOS to file" thingie in GPU-Z and send it if it would help in any way?
In either case I'm just glad you guys put out a tool like this so please do not take me being bummed if there is nothing that can be done to detract from that.
too much work for me for what would be gained
Shame I will never see any of the GPGPU-Boxes checked... Hate Ati for making the HD2xxx and 3xxx-Architecture unable to process GPGPU stuff; but hey, by the time it gets properly used I'll have a new laptop and hopefully a HD5xxx Mobility or a Fermi-Mobile GPU (don't quite think it'll make it in time :o ).
Is it even possible with ATI cards?
This app just keeps getting better and better.
Thanks mate.
