High CPU usage

[christopherve7alb]

I have just installed Sling Front and so far am fairly impressed with it; I do have one issue with CPU usage though.

I notice whenever SlingFront is streaming video (source is a SlingBox Pro HD) the CPU caps out at 100% (640x480 SD resolution). If I try and stream HD the video stutters and is unwatchable.

I am running SlingFront on an Acer revo PC; Intel atom 330 (1.6GHz) CPU, 2GB RAM Windows 8. This is a clean install with no additional programs or software installed. I have verified that the only thing using CPU is SLingFront.

Is this expected behavior or is there something I can do to optimize the performance of SlingFront?

You may find some answers here. Consensus seems to be that you are running on a machine that is underpowered for what you are attempting to throw at it. My guess is that you are using the integrated graphics which, on some higher-end machines will work fine, but not with the mobo/CPU you mention.

Thanks for the reply. After doing some more testing, the CPU usage problem only occurs when connecting to my SlingBox Pro HD and not my second SlingBox Pro. I suspect the difference is that the SlingBox Pro uses a WMV stream (640x480 causes about 20% CPU) while the ProHD uses an h264 stream (640x480 causes 90% CPU). According to this forum: http://placeshiftingenthusiasts.com/forum/slingbox-hardware/slingbox-pro-best-firmwareslingplayer-version/page-2/ it used to be possible to force the older SlingPlayer application to prefer WMV over h264 streams. Is there any way to force a stream preference on SlingFront?
