GPU usage?

I know ATI can display GPU usage, but is there a program that will allow us to see this on nvidia cards?
 
You can use RivaTuner to monitor video memory use by adding it to the graph (hardware monitoring).
You can graph fps too, does that help your cause?
 
well, im trying to see if CUDA technology really comes into play when using premiere CS4 encoding h.264 videos... The nvidia website says so, but I want to see if it does. My quad core is 100% usage the whole time, but the videocard temperature still stays the same idle, so I'm not too sure.

check your driver version and/or download the phyx extensions.

You can graph temp in Riva Tuner.
By mapping which temps are associated to % GPU use, you might be able to get some idea of the GPU use.
(ie set a load and measure the temp after a while)
The temp will need time to settle so no instantaneous results.

I'm sure you can find something better but thought I'd mention it.
 
so by consensus, is rivatuner the only way? I don't understand why nvidia can't make it easy on us :(
GPUz works with ATI to show usage, but not for nvidia lol
 
well, i know it works for physics if that's what you're asking... but for CS4, i do not know if it's utilizing CUDA or not.
 
CS4 & GPU accelerated effects

so what ? Adobe wakes up and realized that nowdays, a lots of power is not used in your graphic cards. And so, you could have very fast processing power to allocate to graphics operations !
(that's why Nvidia build their own way of programming their GPUs using CUDA specific language. more on CUDA on another post...)

that's mean that some effects are now REALTIME !!!
but they use OpenGL instead of directX, so you have some limitations...

OpenGL/GPU features in Adobe Photoshop CS4 are:
Smooth Display at ALL Zoom Levels
Animated Zoom Tool

Animated Transitions when doing a One Stop Zoom
Hand Toss Image
Birdseye View
Rotate Canvas
Smooth Display of Non Square Pixel Images
Pixel Grid
Move Color Matching to the GPU
Draw Brush Tip Editing Feedback via GPU
3D GPU features include:

3D Acceleration
3D Axis
3D Lights Widget
Accelerated 3D Interaction via Direct To Screen

oh ok, it makes sense now... So i guess that's where workstation videocards come in because CS4 doesn't use DX, but openGL?
 
Is there a way to make the openGL that's supported on the gaming cards to be useful in CS4?
