Thank you for the info.

There were a few threads on this topic in the past, but the mod(s) kept moving them to the "Linux and other systems" area, which no one followed them to, so they just died.

Mods: please get a clue. Yes, it's a Boot Camp topic, but more importantly it's an iMac Pro topic, and there are potentially many new iMac Pro owners looking for such information here.

The forums become much less useful if you immediately file everything at the bottom of a locked filing cabinet stuck in a disused lavatory with a sign on the door saying 'Beware of the Leopard.'

This is very very good news.

As said its a little workaround. But is should work perfectly.

The drivers is the most important thing, the other stuff is not important. Only if you are overclocking.

I tested to game on OS X today, it sucked!

Tomorrow I wil install windows and install the custom drivers and test, I think it will work A LOT better.

They should have an own thread on the iMac Pro on this forum...

Will try first with standard drivers and compare to the new ones =)

Can you overclock and undervolt with MSI Afterburner using the new Bootcamp drivers?

yes, you can change memory clock and core clock .. you can not change the voltage

Ok, thanks. Too bad about the voltage, because the Vega is supposed to be undervolting well, which would give more performance with similar thermals.

As you can see above, the scores are not better with the new drivers, it´s the same or a little bit worse

yep, as of right now, you can´t change voltage. We must hope it will be compatible later.

Yes, i have the 64..
i think it will be better with a clean driver install

Scores in firestrike around 16500 can maybe get up to 19000 but thats the limit..

So the graphics-card is like a gtx 1080

I got it working now.
I can say that the new drivers, make many games much faster!
The games I tested before was not much difference, but for example Witcher 3, did not work at all with the normal drivers, only 3 fps. Now steady 60fps.

I´ve made comparisons with PCs my friends have..

The Vega 64 is like a GTX1080 with corei7 7700k in gaming performance, (not benchmarks)

------

Actually, if you think about it, its very impressive to get all that performance in that little case. Even if you're gaming, the fans do not work that hard.

The screen on the iMac Pro is amazing for gaming! Actually I like this more, than a 165 hz gaming-screen, yes its nice with high frame-rate, but the colors on Apples screen makes everything pop so much it looks like 3D.

Sounds impressive. How often does the fans ramp up, and how noisy are they (compared to regular iMac w/the top GPU option, and especially demanding dx11 and dx12 titles that stresses the GPU)? I'm curious about how powerful the new thermal system is, it seems very good. Enjoy your iMac Pro! :)

Its not loud at all.

You do hear the fans, but its so low pitched and soft. So it does not bother you at all.

If you feel on the back the air that comes out is hot! But there is no throttling.

I´ve tested games with the absolute highest settings you can get. and everything works great (with the new alpha-drivers) But the Benchmarks as said, is no different in the results. But if you think about it, that does not matter, its the performance in games that matters.

The resolution is of course not 5k, but 2,5k. But you won't bother it looks so crisp!

The fans never max out, I choose in games that it will stop at 60 hz, so it never get very loud. Compared to a normal iMac the fans are MUCH quieter. Even if it works hard, its. as I said, a more soft sound.
I´ve tested Wolfenstein 2, Call of Duty WW2 and Battlefield 1.

But the Witcher 3 stands out, with its beautiful landscapes. On the iMac Pro it looks like you see it through a window.

Impressive! :) I’m about to pull the trigger on the iMac Pro, but I‘ve been a bit sceptical of going for the Vega Pro 64, as a silent computer is important for me. The Vega RX 64 has been frequently criticized for being very power-hungry, and running considerably hotter and noisier than Vega RX 56. Even though the iMac Pro 64 version is downclocked, it’ll put a lot of demand on the thermal system. From your findings, it sounds like Apple did their homework with the iMac Pro...nice.

I think the 56 will be enough.

Apple always get very good quality on their stuff, so I don't think there is that kind of problems on the iMac PRO.

Yes, you don't have to worry about the fans. Myself, I HATE loud fans, when I bought my last Gaming-PC, it was very quiet. This of course sounds more because its infront of you. But its not annoying. More lika a "ppffffff" sound than "eeehhhhhh" The room-temperature is around 20 degrees, not so hot (live in Sweden)

But in Windows (BootCamp) there is something strange with the speakers, it sounds... off.. and after playing some games, there will be strange stuttering noise in the speakers. You then have do deactivate them and then activate them again, and then its fine.

But that is a thing a software update will fix.

---

Its a expensive machine, but you can do everything on it. And in a couple of years when graphic cards is so much faster, you can use a eGPU.

In the future there will be dual Thunderbolt 3 ones. they will work as a charm =) with almost no loss in performance.

Thanks again for the info, appreciate it! Norway here, btw. :) Are you certain the GPU is not throttling over time while gaming? Would be really interesting to know (w/demanding games in high res without framecapping).

Anyways, enjoy your iMac Pro! Vega 64 is a very powerful card, and should last a long time. Hopefully Bootcamp drivers will improve over time, Apple kinda dropped the ball here.

I can make screenshots of the results =)

But it´s strange, as I said, in the benchmarks the scores are not higher, but in many games, it works a lot better with the new drivers

I am not 100% sure that it´s not throttling. But I do not get performance-loss, and the fans do not go on full-speed.

I´ve tested my PC against the iMac Pro.

Its a:
Core i7 8700k
GTX 980Ti OC

In 3d mark firestrike, it gets around 17500 points, thats 1000higher than iMac Pro.

But with the hacked drivers on the iMac pro, you get better performance in games as Witcher 3. Its steady 60 fps in 1440p. But on the PC it comes down to around 55fps sometimes. Often lays around 77 fps.

-----

So thats makes the iMac Pro comparable in game performance to a gtx 1080...

In the future you can get a eGPU to boost performance, or a PC in the same network, where you can stream games via steam connect

Is Bootcamp still working for you? I heard that after a few reboots, that Bootcamp will become unstable (driver repair, uninstalling drivers, not starting etc.).

As of the latest Adrenalin update 18.2.1 for iMac Pro, testers have confirmed the boot loop issue is no longer there, and FPS has improved further still in many games.
