Seems with all this trouble with the i3, I'll just stick with my current setup, or use AMD.

Again, only for intel and only for 10.1 official release.

What is considered "good"?
This one works great for me.

I still want HW acceleration as I hate the HSF that comes with the 2100t as it is loud and makes a high pitched whine. I have it set to idle at the lowest setting (completely silent), but without HW accel, temps go up and the HSF is audible.
Using MPC-HC with DXVA on the other hand keeps things perfectly silent during playback, and temps are much lower on the whole.
Sorry for the late response. Kinda lost track of this topic since there are quite a few out there. But to answer your question: yes, i'm quite sure the CPU isn't being throttled. I haven't checked temps, but I instead of the 2100t stock cooler I used the cooler that comes with the 2500k (which is nice and quiet most of the time). Most videos play fine, but I have a few with quite high bitrates. A 25GB rip of Avatar drops frames quite often for instance. I'm not the only one in this thread with this problem. I discovered Xbmc uses just one core for decoding video. The 2100t doesn't have turbo, so I think that's the reason why frames are dropped sometimes in high bitrate scenes.
Right now I am looking at ways to work around this problem. The only option I have found so far is using an external player. I'm trying to get MPC-HC to change the refresh rate to 23.976, but somehow that won't work. 24.000 does. I know SB has 24p issues, but I also know XBMC manages to output 23.98hz. Somehow MPC-HC won't do that... Orion2001 (or anyone else), did you run into this problem?
If I manage to get this to work, there is still one (for me) mayor issue. I just realized the XBMC menus won't work when using an external player (doh...). This means the XBMC subitle addon (which I use a lot) won't work... Anyone knows a way around this?

Make sure UAC is turned off within Win7....Otherwise a new intel driver update is supposedly in the works that should fix the issue.

Already tried that. didn't work unfortunately. When i enter full screen mode playback stops and won't resume. I can still see the osd and press play/pause, but screen stays black... Using the latest xvid.ru build btw. But it's not really an issue, using an external player isn't a proper solution anyways.
Looking forward to the new intel driver. I hope it will fix some issues, but to be honest I doubt it...

Just for reference/comparison I have:
- Sandy Bridge i5 2300 on an Gigabyte H67 MicroATX board
- 6gb memory
- SSD drive
- Win7 Home Prem. 64bit
- using Intel graphics (no discrete video card)
(edit) - also running XBMC 10.1
meridius Wrote:I am building a new system soon and was going to go for the i3 but does this problem hppen on the i5 as well ?
Yes, the h/w acceleration issue is there with the i5 as well. I built mine back in February and when I first fired it up I was like WTF! regarding the pixelation. Then diddled with the settings and flipped it to "software" and all was good. Didn't think much of it as to me h/w graphics acceleration is about handing off the video from the cpu to the discrete video card...but since the Sandy Bridge setup does it's video with the cpu...h/w acceleration would be the cpu anyway. So I just figured that was how it went with Sandy Bridge configs...
meridius Wrote:if it does and turning off HW acceleration would it handle high bitrates as some people said the i3 can not handle some high bitrates.
Yes, my i5 system is just fine running in "software" mode instead of DXVA h/w acceleration. No performance issues, no pixelation or macroblocking whatsoever on anything I've played on it for the past 6 months in SD or HD (and I have an extremely extensive media collection...LOL).
I just sampled a few 1080p BD rips (MKVs) playing through their heavy action scenes with lots of on screen activity and performance traces average about 12-15% cpu with the occassional momentary spike to 20% during these heavy action scenes (across 3 of the 4 cores, the 4th core is minimal 2% usage during the same period).
Note: All my HD content, I've ripped from my BD using Handbrake and such to smaller 6 - 15 Mbps bitrates (works for me, my eyes can't see the difference from the higher/native BD bitrates...LOL)...so I can't speak to the native higher bitrates (25Mbps+).
So for me, I've no issues whether the h/w acceleration problem gets worked out...it doesn't impact me at all. I'm actually glad the guy at my local computer store pointed out it was only $40 more for the i5 part versus the i3 (also with not much of an increase in heat he said)...'cause I was gonna get the i3...

Any updates? :x:
- Balinus - 2011-07-21 14:54
I'm wondering if the i3 is enough power to not only decode HD content but also do de-interlacing of HD content in XBMC?

Haha, well the reason I'm back at this thread is because I ended up coming to exactly the same conclusion as you yesterday! I finally watched my 25+ GB RIP of Avatar yesterday and was quite annoyed with the frame dropping in the action sequences. When I looked at the processor utilization, it was quite disappointing to see that only a single core was being used.
It's also quite disappointing to see that there still isn't any support for Sandy Bridge, not even in the nightly builds
. SB has been out for a while now and the MPC-HC devs got hardware acceleration support into one of the nightlies almost immediately. I wish I knew anything in this area to help contribute, but unfortunately I can't...and it doesn't seem like this is a priority at all with the folks who are developing XBMC.I'm thinking of ditching XBMC altogether at this point as I really need DXVA for my HTPC. MPC-HC works like a charm for now and I've been using it as an external player. However, as you mentioned, that doesn't work too well and it isn't the best way to have it setup when others in my family try to use XBMC.
