There clearly is a difference and I usually edit my videos so I'll have to render them again.
The max Mbps Shadowplay can capture at is 50 which already is compressed. So If I'm going to render it again it'll get even more compressed and uploading it to Youtube will butcher it even further.

Suffice to say, I suppose it's watchable I guess since Youtube is already horrible with its compressions. I've seen some Shadowplay footage uploaded to it.

50 mpbs is 10 times what youtube is going to compress it to......

I can't notice the difference between 5 mb/s and 50 mb/s on a 1080p h.264 video locally unless I use a really garbage encoder with fast settings (which granted you have to do when doing video game capture). Do we even know anything about how shadowplays quality/efficiency is going to stack up against the fast x264 encoders that everyone is using for streaming these days? I mean if its even equivalent to the medium setting on x264 there is no way you're going to be able to see a difference.

But why?

Why would you spend all that money on something that isn't going to improve your performance?

The exact opposite has been the case. Thermal tolerance and dissipation have been increasing every year over the last decade for GPUs.

Excavator will be at the least gtx 260 level. It will be using DDR4 which will boost it's memory bandwidth.

Are you serious? There's a humongous difference.

I've made a comparison just for you, it's not the best, but it'll do.
5mbps
50mbps
lossless

Yes, 50mbps looks good, but in more detailed scenes or fast moving scenes it'll show its weakpoints. It's good enough though if the performance hit is really negligible.

Haven't checked the specifics yet. Did you try it out yet?

[NaturalViolence]

You have not stated what encoder or settings you used. Note the part where I said "unless I use a really garbage encoder with fast settings". The difference between 50 mbps and raw in this comparison is so small that there is no way you would be able to tell the difference in a video (though maybe in screenshots).

No. I'm waiting for the official drivers.

Why would you spend more money to "upgrade" to something that will give you the same performance as what you already have? That just seems like a waste of money.

You're right that in 2 years a top of the line IGP may be able to beat a GTX 260. Though I'm still skeptical since the GTX 260 has 120GB/s of memory bandwidth which is going to give it a serious advantage in any memory bound shaders. And DDR4 isn't going to get anywhere near that fast. Expect maybe 50 GB/s since it's expected to double the operating frequency while maintaining the same buswidth. They might be able to get around this a bit with sram and/or edram caching though. We'll see.

Sorry was too fixated on getting you that comparison.

I used Handbrake, with slightly altered settings:
- x264 preset slow
- h.264 profile high
- h.264 level 5.2
- average bitrate 50000kbps

I've got both video files here and looking at them both, the average user wouldn't notice the difference yes.

[NaturalViolence]

You used those same settings for the 5000 kbps encode correct?

[garrlker]

Shadowplay is good and all but using the rolling buffer just used up all of my C: drives hard drive space. The recording drive is set to a spare 500 gb harddrive I had so I don't know why C: is used up. Anyone else noticing this? I can't even find the recordings to erase them.

Indeed. I only changed the bitrate there.

r9-290 for $10,000?!?! It better be 10x better than the titan. >.>
