I'm wondering if the regular Nvidia notebook drivers install okay under Windows with no mods/hacks on the new 2013 iMacs. My understanding is they do for the Macbook Pro, but wanted to make sure they do on the iMac.

For that matter, do the Iris Pro drivers install without issue on the cheapest model?

Well, the NVIDIA drivers from NVIDIA themselves didn't install properly on my rMBP with 2GB GT750M, so I had to stick back to the stock Boot Camp drivers.

I haven't checked back whether NVIDIA has released newer drivers or not yet.

Darn, that's disappointing.

Thanks!

Oh and by the way on my 27" iMac, the drivers from NVIDIA worked though.

4GB GTX780M

Thanks! That is weird...I wonder what's going on and whether the 21" model would work. Did you try it with a recent mobile driver release? maybe it just didn't work with the drivers available when the system first launched?

Among other things, I like that the Apple computers have less weird chemicals in them than other brands :-D

Yeah I used mobile drivers which worked upon release, surprisingly. Different story for my RMBP though. I'll be testing it out once I get back to my country.
 
I'm using the most recent drivers from NVIDIA website and have no issue installing or whatsoever.

On my iMac 27 2013 (780M).
 
running the latest cuda drivers from nvida on my iMac no issues.
 
I tried BF4 on my maxed out 27" with the latest drivers from Nvidia installed ( 9.18.13.3182 )

With AA off and High visual details, the game runs fine and there is no lag or dropped frames whatsoever but, it doesn't feel smooth.

I don't know how to explain it but say you're turning around a vertical line, you can see at some point that the line isn't straight anymore but two parallel continuous lines ( something like ----____----__------ )

Pardon my explanation but I can't describe it better. It's not aliasing because AA didn't help.

Not sure if it's the Nvidia driver or... the Nvidia driver....

It's screen tearing. Glad I'm not the only one.

But I don't have this issue when running BF4 on my dual Titan-SLI gaming rig at home.

##I too don't have it on mom's 8 Core 4 TB RAID 10 SSD 2x ASUS ROG ARES II 64GB RAM 4K Asus display cheap PC ##

Must be the driver...

I think it's really the card itself. The iMac uses a GTX780M, not GTX780, so probably we've already pushed the card to its limits.

but it's the same thing on MW2 even with 300+FPS at native resolution and 4xAA

IA64,

Have you tried beta drivers ?

Hi Silvetti, no I haven't but to be honest, the latest drivers are a month old.

So far, I am afraid to say that the 780M did not impress me at all :(

I still need someone with a late 2013 iMac to send me a printscreen of his Device manager section, the one in the picture specifically :

I can do that later when I get home.

Here it is, as promised :)

Thanks. Basically the same installed.

I identified the issue with my not so smooth iMac.

The light sensor is causing issues. In event viewer I can see :

The driver \Driver\WudfRd failed to load for the device ACPI\ACPI0008\4&22bfcd45&0

That's causing 10% CPU usage randomly in background by Windows User Driver Foundation.

ACPI0008\4&22bfcd45&0 is the light sensor and looks like we I need to find a better driver. Mine is the one Windows installed.
