Upscaling SDTV to 1080p with a Core2Duo 2Ghz? (1 Viewer)

[Nybbe67]

Hi
I have an 3-4 years old HTPC based on Win7 and MP 1.3 beta and a brand new Sony HX855 55" TV and I want to upscale everything, SDTV, DVD, movies to the TV's native resolution, 1920x1080p.

My computer is based on an Intel Core2Duo 2Ghz with 2 GB RAM and a SSD disk for Win and MP(system and timeshift) and a Nvidia GT430 GPU. All latest drivers installed.

Im trying to upscale with postprocessing with FFDSHOW tryouts RAW filter but its not playable at all. It is stuttering so much that it allmost hang the pc, so much that I cant see the load of the cpu.

Are the CPU too weak for that or is it something else?

none?

Hello,
I think your CPU is too weak.
Did you follow this guide to upscale and improve video quality?

What is your CPU activity during SD video? You will have your answer by looking at it.

Yeah, I think so too because I have another computer with a I5 Quad 3.3 Ghz CPU and its working.
But I cant see the CPU load on my primary HTPC because the cpu stops for a little bit, every time. Its freezing, not totaly, and then it will come back.

Yes CPU is too slow, I would just let the GPU's inbuilt scaler do the resizing. ie. you do nothing except set the desktop resolution to 1920x1080.

To get the smoothest playback I would use the default refresh rate changer as well as the new MP Audio Renderer (Check the MP wiki for how to set up the audio renderer)

Im allready running at 1920p resolution and refresh rate changer but not MPAR. Got som problems with the sound then.

Im never satiesfied with the picture if its there is a chance to get better picture, therefore I tried to upscale it.

I dont think upscaling does a lot really, if you want better picture then download bigger files

 

[Nybbe67]

Its the upscaling of SDTV thats most impotant. Im allready downloading the biggest files.
Im trying too squize out what I can with the pc to get the most out of it.

I know, if I get HDTV its better but I cant get all my channels in HD.

upscaling sd live tv will require more resources than upscaling sd video

You mean more CPU power?
