Topic: GPU-acceleration not working / CPU only being used

Hello SVP community! I am trying to watch a movie with at least a frame rate of 60. My problem is, when I try to play the video, the output is not real-time speed. I opened the Windows Task Manager to see my CPU usage is around 100% and I opened the ATI Catalyst Control Center to see the GPU activity is 0%! I need help!

In the SVP Manager, I have "GPU-acceleration (OpenCL)" enabled, but the GPU is not being used.

I have a video of what happens when I try to use SVP.
I had no background programs opened or background services started besides Microsoft Security Essentials at the time the video was recorded.

1. What you see in dialog: SVP tray menu - Video profiles - Reset to defaults?
I mean current profiles name and selected profiles name.

2. Please show your additional info while playing this video. SVP tray menu - Information - Additional information.

Why you selected this value of setting "Target frame rate: Source multiplied by 4 (4x)"?

Prees OK in the Reset profile dialog and you will get optimized profile settings for your system performance. SVP detects your system performance level as "2g".

I had it set to "Source multiplied by 4 (4x)" as an example.

I reset the profiles to default and there are no results of any slowness. I do mind the artifacts though which was another reason why I had the settings set to the maximum. Even with the default profiles, GPU activity / load is still 0%. I check with both the Catalyst Control Center and GPU-Z.

I think if the GPU-acceleration worked properly, my GPU would be able to handle those settings just fine, or if the settings were tweaked a bit lower.

Re: GPU-acceleration not working / CPU only being used

What SVP index value do you see in the Performance graphs window: SVP tray menu - Inormation - Performance graphs?
And what this value becomes when you disable GPU-acceleration?

With GPU-acceleration = 0.97-1.01 / 0.99
Without GPU-acceleration = 0.98-1.01 / 1 (Sometimes jumps to >1.5)

Re: GPU-acceleration not working / CPU only being used

If you point mouse pointer to graphs then you can see average meanings of SVP-Index and CPU load. You must notice difference in values when GPU enabled and when disabled.

Re: GPU-acceleration not working / CPU only being used

I have the same problem and an additional one.

After installing, SVP only uses the CPU despite GPU acceleration being enabled. After resetting the profiles, it stopped working completely and no longer detects videos playing in MPC-HC.

When it worked, it managed 60fps at 1920 on the CPU alone, barely (2600K @ 4.3 GHz), but it should run way better once I get it to work on the GPU (an overclocked Radeon HD9750).

I am yet to restart my system to see if that helps because I currently cannot do that, doing some uninterruptable stuff.

Any suggestions on how to fix it?

Recalculated at default screen resolution.

With GPU-acceleration: 0.75
Without GPU-acceleration: 0.59

The index would spike with GPU-acceleration.

Re: GPU-acceleration not working / CPU only being used

After some reinstalling and testing I can confirm that the GPU acceleration actually works for me. It just doesn't register in any GPU load programs, probably because it's not actually rendering frames via GPU completely.

5g profile works reasonably well for me now. Around 60-70% CPU on difficult files. That's on a 2600K @ 4.3 GHz, 7950 Vapor-X radeon @ 1150MHz (1400MHz memory, voltages raised a lot to allow for it).

We always knew that  big_smile
As far as menu item is checked and there're no errors - it works.

May be there's some bottleneck in your setup, so pass SVPmark tests and post results to the server so we all could check them.

Re: GPU-acceleration not working / CPU only being used

looks fine...

- turn off ALL video processing / enhancements in Catalyst
- what is renderer in the video player - switch to EVR

Enhanced Video Renderer appeared to fix it! CPU Usage is minimal and I can hear the GPU fan at it! Many thanks!

Re: GPU-acceleration not working / CPU only being used

both things (madVR and video driver's "video quality" options) are dangerous
especially if you don't know where to look smile

Re: GPU-acceleration not working / CPU only being used

I may have a new problem. The GPU appears to have activity, but not much. The activity shows 30% then jumps to 0% then back to 30%. The CPU Usage has gone down around to 70%. Also, I can't see any visible interpolation unless I lower the mode until I see major artifacts. The video is realtime. The index is around 1, but I can't notice any improvements. Also, I can switch between EVR and MadVR without any noticeable differences in CPU and GPU usage. MadVR shows interpolation better than EVR does. Maybe the problem was with the Catalyst? Usually I would notice a constant speed improvement on the frame rate, but now it just appears to improve on the slightest movements that don't make much of a difference. SVP actually appears to be trying less than it did before.

Does video has motion in EVERY frame? Maybe you try to watch "unsmootheble" video. Try another video.
You always can enable demo mode to compare smoothness before and after SVP: SVP tray menu - Demonstration mode.
Maybe you have problem with renderer? Run tearing test: SVP tray menu - Tearing test. Orange line must move smooth without any jerks.
