The Rift finally arrived and I got it all set up last night.
Pretty cool. Hooked it to a nMP 6,1 12 Core and an eGPU GTX1080. Smooth as silk!
Will be trying on a cMP 12 Core soon. I will also use a USB 3 card with that, but try with USB 2.
Nice to see that there are 1 or 2 Macs that are up to the challenge. Tonight I will download "Valkyrie" and try that.
Does anyone know of a good VR benchmark?
I realize it's kind of tough to do, but there must be a way to comnpare, beyond the subjective.
On another note, the "Catatonic" VR movie creeped me out. Definitely more scary than watching a movie on a TV. Turning around to see who was pushing me and discovering that the orderly was gone, and a psycho had replaced him was something. Also enjoyed the demo with the T-Rex attacking.
UPDATE; After several days of testing I can report that it is quite stable and solid on 6,1 nMP.
We had someone ask about the DP to HDMI 2.0 adapter and I was skeptical. So I got one.
And IT DOES WORK WITH MACS BEAUTIFULLY !
Even on a underpowered DP port from a 2014 Mini I was able to output 4K 60Hz HDMI to a 4K TV with HDMI 2.0 input.
No drivers, no settings, no nothing. Just plug it in and enjoy the 4K experience.
The one I got was from Micro Sata and was $30-40. There is also a hack I have been made aware of to enable higher pixel clocks, haven't tried that yet.
The fact that a simple adapter can produce these signals tells me that Apple has deliberately crippled certain setups and thus it is likely that the hack also works, or could.
Anyhow, I was even more amazed when I went to try the adapter on a MacBook Air. I was copying things to a TB drive and realized that the Air only had 1 @ TB/MDP port. But my Akitio chassis had a TB Daisy Chain port. I plugged it in there and had 4K 60Hz HDMI ! (While Restoring a PCIE SSD at same time)
Nice little product, might grab a couple dozen and stock them.
Turns out Sierra works even better with eGPU than did El Cap.
With EFI eGPU on nMP complete functionality, no system hacks needed.
Just wanted everyone with a 4,1 or 5,1 to know that we have slipped under the knife one more time.
The 3,1 will require a few tricks to work with Sierra but so far the 4,1/5,1 are easy breezy.
Hopefully they don't titghten things down in the final GM.
In other good news, Nvidia has already released a Web Driver for 10.12 (see our drivers page) and it has HINTS of Pascal support. So I'd say it's a fair bet that we will be seeing GTX1080 and GTX1070 running on cMP soon.
Hats off to Nvidia for standing by us as Apple continues trying to become a toy company.
So here it comes.
Looking forward as I have not tried one yet.
Will try on the 12 Coe nMP and 12 Core cMP. Will use GTX1080 with both...because I can.
BTW, the GTX1080 with nMP is a dream in Windows. Have Doom running on a 65" 4K TV. Immersive. And it does pretty well on 3DmMark.
Good news, you can use the already released 10.11.5 Beta Web Driver with the Final build.
I'm sure that Nvidia will have their Final version out within 24 hours but if you already ran the 10.11.5 update, no worries, the Beta works !
UPDATE: As usual, Nvidia had final driver out within 24 Hours. Quick round of applause , please.
On our drivers page.
So the earth shattering Pascal cards have been announced. And our email has been blowing up about when we will be shipping EFI versions.
Time to take a breath. We can not say for certain that Nvidia Web Drivers will support Pascal series cards. It is likely that they will be supported. Once they do, we can get to work on an EFI for them.
But I have to warn you that depending on timing and other things going on it may take awhile.
Please don't email us about these cards. As we make discoveries they will be posted here and at the usual forums.
Thanks for your interest, will be an exciting time !
Prowling various forums (and Ebay) I notice that many 2009-2011 iMacs suffer from frying GPU cards. The problem frequently is that the price of replacements is near (or more) the value of the iMac being repaired. This is probably sending many iMacs to the landfill prematurely. Several people have reported that some PC MXM 3.0 cards work in these iMacs, but due to the lack of EFI, they have MANY issues. In addition to losing boot screen, they also lose brightness control as well as external displays, and the ability to use bootcamp. I fell quite confident that we could write working EFIs for many cards, most likely the Nvidia ones would be easier, but it is also possible that some AMD cards could be made functional.
In any case, we could allow people to replace dead GT120s with 256 Megs of RAM with GT630s or 650s with more modern support, and no more power draw or heat given off. I can tell you a little known secret, there are already flashed iMac cards being sold, but the sellers are clever enough to not mention it, they are thus able to collect the "Apple Tax" without anyone noticing.
What MacVidCards needs is a local Los Angeles partner to work on these with. I do not have the space or time to work on iMacs. But I will soon have the means to test OSX functionality with any and all MXM 3.0 cards. This will lead to the ability to write and test iMac roms to greatly expand the options for iMac repair. The ideal candidate to work with us would be a facility that already does iMac repairs. Replacement cards are hard to come by, we could greatly expand the options, lower prices, and allow a repairer/reseller the chance to market the cards. To really and truly test the cards would mean eventually trying them in each and every Mac that offered MXM 3.0 cards.
The good news is that once they are tested and finished, it will be much easier to crank them out. Currently used iMac GT120s fetch a minimum of $200, while new ones get $600-700. We could make it possible to offer MUCH better cards, for less money. And that would also allow the "real" Apple cards to drop in price. Win/Win.
So, who has some space and time? I'm confident that there is serious money to be made, while simultaneously doing some serious good for the Mac/iMac community.
I recently got a box of 7970s that were supposed to be in perfect shape. Out of 5 cards, only 2 were able to complete the Uningine Valley test twice in a row. And I'm afraid that was the last straw. The AMD Tahiti cards are the last ones with full driver and EFI support. Lots of people want them, and when they work, they work pretty well.
However, some time back I noticed that although they represented 20-25% of our sales, they were easily 50-60% of our returns. I have far more dead 7970s than I do dead Nvidia Kepler cards. Getting stuck with dead cards is a bad deal for us. As it was, we had to double the stress tests for the cards to catch more bad ones before they shipped to our customers. But having 60% failures in one box was too much.
We may occasionally offer some R9 280X cards when we find them in reasonable shape, but I can't justify the time and expense of testing cards that fail so often. The older 7950 and 7970 cards will no longer be stocked by us unless I stumble upon some really choice ones.
We will be happy to flash them for our customers, but suggest that when you buy them used (no new ones made in years, so no choice really) that you test them thoroughly before sending them for flashing. The standard failure mode for these cards is either screen going black while machine keeps running, or entire Mac Pro shutting off due to excessive power draw. Run that Uningine Valley test on "Extreme HD" at least twice in a row to weed out the bad ones.
Many of these cards spent their early lives in Bitcoin setups, running at 100% 24/7 for months on end. And, as we all know, AMD cards are not the best in the performance/watt area, this means more electricity gets used heating up the card versus getting work done. (Like comparing an old incandescent bulb to a new LED one.)
We have a few "oddball" ones that we will be listing soon, a couple single DP ones, and a couple where the HDMI port only works in certain circumstances, etc. These will be pretty inexpensive, but they will be the last.
If someone knows of a source for some good, non-thrashed 7970s I'd like to know.
Fired up a Hybrid Titan-X on nMP 6,1 12 Core and threw it at "The DIvision". The game has approximately 1,000,000 settings so I just left them where they were at default to start.
It managed a reasonable 28.3 FPS. Considering that Guru3D got 35 FPS on their system, I'm pretty pleased. TB2 only cost a little bit of juice. I'll try it with a few other eGPUs in next few days but unlikely that anything will be faster.FWIW, it also says that CPU Avg was 17 while GPU was 94, not sure what those mean, but we will find out. Though I may play with the Shadow settings next, apparently Nvidia cards can do some pretty intense shadows effects now.
Updates to come.
