This is an experimental build made with VS2012, Microsoft's Visual Studio Development Environment. I'm not sure when or if we're going to move to VS2012, but I wanted to give it a try for a build.

This build will not install automatically as part of the update channels because I'm not sure if it's good.

The only missing piece I'm aware of is that the Chromium web browser engine. You'll have to pick 'IE' in Options > Tree & View.

It would be interesting to post your JRMark results with 18.0.70 and again with this build. For me, it's around 4% faster.

For me it is 3514 with 18.0.70 versus 3633 with the new build. So a healthy 3.4% total improvement with the image benchmark having especially improved. I will test stability shortly.

I went from 3524 (just beating out TheLion

) to 3746 so a 6.3% increase for me.

Nice jump in the Image category.....

FSE mode (ROHQ/madVR) with DVD playback is kooky. Jumping from windowed to FSE, the screen goes blank, then it seems, the DVD resets and the load process starts again. Windowed mode seems to work as expected.

SSE?

There's nothing we've done to help JRMark.

So the differences are entirely the compiler.

The compiler probably is using more SSE by itself. It's also doing a better job compiling SSE intrinsics (the SSE code we write) into machine code.

Since CPU architectures change with time, it sort of makes sense that a newer compiler can make choices that perform better on newer CPUs.

The HTPC defiantly feels snappier to me when launching content. Could you try re-compiling in VS2013 and see if you get another 5% improvement for free

kensn · « **Reply #14 on:** November 08, 2012, 09:15:54 pm »

Well not sure what the cause.. but ...

I was looking at my cover flow for movies and was experiencing the stutter that was mentioned in another thread. I went back tonight to look at it is noticeably smoother.
This is on a Nvidia 560.

I vote that you try it for say... the next 71 Builds!

TheLion · « **Reply #19 on:** November 09, 2012, 01:30:37 am »

I also vote for making the switch permanently. I am neurotic enough and open to any kind of placebo effect so to get the impression that this new build feels a touch "snappier". But no, I don't think it sounds better...

I personally had some issues with VS2012 when building LAV, so i'm not switching yet myself.

Sounds like its either using CPU instructions that your CPU doesn't support, or OS features which are too new for you.

Or the good old corrupted download, most likely. :p

i read about the change to SSE2, even though i dont have a new computer (2005) according to everest it should support it, or am i misreading

Following is a quote from the Microsoft document (http://msdn.microsoft.com/en-us/library/windows/hardware/hh975398.aspx) referenced in the other thread about SSE2.

Quote

Streaming SIMD Extensions 2 (SSE2) is a previous standard that is supported in Intel and AMD processors. All processors that support NX also support SSE2. Many Windows 8 applications have code paths with the SSE2 instruction set. Performance optimizations in the latest versions of Visual Studio are enhanced to generate SSE2 instructions by default. To prevent these applications from crashing when running on a system without SSE2 support, the SSE2 support requirement is also enforced in Windows 8.

If it does not introduce serious issues, I would say GO for it

They removed XP support. Lots of people complained (surprise!).

Fortunately they've released an update to Visual Studio to allow compiling something that runs on XP. A little more here:

Hendrik · « **Reply #28 on:** November 09, 2012, 09:30:33 am »

At least they released an official CTP update already to allow you to target XP again.

Personally, i think supporting an 11 year old OS is equally bad as supporting equally old CPUs without SSE2.

MrHaugen · « **Reply #30 on:** November 09, 2012, 12:24:31 pm »

Ruling out XP would not be a great idea.... Yet. There's still quite a few around.
If it's easy to make it compile for XP, I have little problem with it.

TheLion · « **Reply #31 on:** November 09, 2012, 01:41:42 pm »

Yes, the problem is that Vista was so bad that many lost faith in MS and just sticked with XP . It seems history repeats itself with Windows 8 - I guess most will stick to Win7 and even XP.

On the other hand still continuing to support an 11 years old OS (as in making sure every new feature runs there as well) requires many ressources from Matt and Co and therefor gets more and more in the way of progress.

MrHaugen · « **Reply #32 on:** November 09, 2012, 02:08:51 pm »

I know. We have a lot of this kind of decisions in our company as well. It's not exactly fun stuff. But I think the best time to do this switch is to follow Microsoft's own end of support plans. That will give JRiver a very good argument as well. As far as I know, this is the current plan for End of Support.

Windows XP SP3 and Office 2003
Support Ends April 8, 2014

jmone · « **Reply #33 on:** November 09, 2012, 02:25:56 pm »

But it is also a balance of what limitations are being placed on those with current OS? Eg we are seeing good performance bumps in the above posts, so to keep with the old compiler is now a deliberate decision to sacrifice performance for those with a current OS.

MrHaugen · « **Reply #34 on:** November 09, 2012, 02:48:26 pm »

OPERATING SYSTEM TOTAL MARKET SHARE
Windows 7   40.42%
Windows XP   36.02%
Windows Vista   5.03%

Other OS not mentioned. This is from October.

With those numbers in mind, you have to think about those 36%. Even though many of them are company computers, there's still a lot of potential users on this aging platform.
