Graphic drivers for retina pro

No, it still requires an inf modification.
The graphics processor on Retina MacBook Pro is identified with a device ID that's different from most other GeForce GT 650M on the market. I suspect that's because Apple "modified" (read: overclock) it to fit their use.
On the surface, it says it's a GT 650M, but the performance is close to 670M.
I have the driver installed, and I didn't require any inf modifications. I have no idea why it didn't work for you (you do speak from experience, I presume). Anyway, you go a bit too far by comparing it to the 670M, the rMBP levels of performance is GTX660M at best — and it has a long way to go to match the 670M.
Edit: Sorry, missed your last post
660M has core clock of 835MHz and memory clock of 2000MHz (GDDR5) respectively.
650M in Retina has core clock of 900MHz and memory clock of 2500MHz and it's also GDDR5.
Unless they have some other fundamental difference that I didn't catch, 650M in rMBP is clearly on par or faster than 660M. I know because I have handled a laptop with 660M before, and my rMBP is consistently faster or smoother in gaming.
That and you can overclock the 650M in the Retina MBP another ~200MHz. I tried. Mine got to 1150MHz core.
Considering 670M is "only" 20% faster than 660M (and 650M in Retina by convention) on average, then it's safe to assume that a 30% boost in clock speed for Retina 650M should be "close to" 670M if it doesn't match 670M. I don't have access to a 670M laptop for comparison, but simple math would show that the 650M in rMBP has the potential to reach pretty high up... assuming it's not limited by thermal.
If you overclock the 650m, it will be even faster than the 670m. If you overclock it appropriately you could even say that its somewhat close to the performance of the 675m then.
Sure, only limited by TDP but it still doesn't change the fact that the Geforce GT 650M can be clocked up to 900Mhz and the Geforce GT 660M is limited to 835Mhz and only that speed.
They are based on the same chip so in most instances where the OEM has clocked the Geforce GT 650M at 900Mhz, it will be faster than the Geforce GT 660M.
The Geforce GT 670M is based on Fermi, whereas the Geforce GT 650M is based on it successor, Kepler.
It also means the Geforce GT 650M and 660M can drive a display up to 3840 x 2160, which Fermi can't.
I have been using MSI afterburner and can only go to 1035 on the Core. And memory seems to be locked at 2000.
I have tried unlocking the MSI CFG file but with no luck. I use throttle stop to disable turbo boost and my GPU stays below 70 in most games. Would to see how far I could push this system.

But rmbp already gets crazy hot as it is! Oc'ing sounds bad.
Are you saying that stock rmbp 650 is overclocked by apple? Why not just put in a 660m to begin with?

I believe if you use NVInspector, you can push it well beyond 1035. 1200 is the highest i have seen, any more than that and the voltage will cause problems..or so i hear. Temperature wise it always seemed to be quite alright.

The price maybe? To put in the 650m must have been more convenient for Apple : Easily to overclock and thus faster and cheaper.
My rMBP doesn't get crazy hot.
I guess it depends on what you do...
And yeah, stock 650 is definitely overclocked. It pushes many games at 1920 x 1200 with High to Max settings like nothing... and if you lax up on settings, you can push some to 2880 x 1800 as well.
I haven't tested much, but I'm definitely impressed by the performance from what I have seen.
Stock drivers from Apple (Bootcamp drivers) was somewhat "weird" to me, so it seems software kinks are yet to be ironed out. Once everything stabilize, I have no doubt I'll see even more than this.
What are some of the games you are playing with 1920 x 1200 with high/max settings? Just curious. Also, how is the 650m closer to a 670m? Doesn't its performance (with OC) put it on par with the 660m?
At stock clocks, it's actually faster than the 660M by a little bit (about 5%).
You can overclock the 650M in the rMBP by another 100 - 150MHz for an extra 10% performance improvement.
But the real limitation is actually with VRAM. 1GB is just not enough for some games.
I listed Skyrim, Crysis 2, and Super Street Fighter IV. This weekend, I'll hopefully have some time off from projects, and then I'll be able to hammer some of the heavy hitters like Max Payne 3, GTA IV...
What are your settings and FPS for Crysis 2? Wouldn't OCing increase risk of system damage?
Gamer settings. 1920 x 1200. It's quite playable. Dropping to 1680 x 1050 gives silky smooth gameplay, but at the tradeoff of being blurrier. I like the sharper look better.
And I wouldn't know either way. I feel the stock settings on the rMBP is enough, so I'm running it stock. I don't game that much anyway.
