The ULTIMATE "Is My PC Good Enough?" (for DK2) Thread

[cybereality]

OK, by popular demand I am making one single "is my PC good enough thread" that will be stickied.

If anyone creates a new thread about this, it will be locked immediately.

Please, this thread should be for DK2 only. Nobody knows what CV1 will need, and if you are only preparing for the next version of the Rift, then you should wait and make an informed purchase at that time.

I will start. I am using a:

- Intel i7-3820 @ 3.6GHz
- Nvidia GTX 680 previously (now GTX 970)
- 16GB DDR3
- Windows 7 64-bit

Mostly all the demos I have tested will work in both Direct and Extended Mode. I haven't done extensive benchmarking, but it's mostly a smooth experience. Some games do have judder, but I'm not sure it's only performance related.

One thing to note: laptops have really poor support for the Rift. Especially with switchable graphics (Optimus) there are hardware limitations that cannot be fixed with a software patch, and will probably never work correctly. If you are buying a new computer today I am STRONGLY RECOMMENDING that you DO NOT purchase a laptop for VR development. You will be sorry if you go down this road and most likely performance will be slow and the games will crash. In almost all cases, a good desktop machine will be significantly better than a laptop you can purchase at the same price.

Please join in with a list of your system specs and if you have a smooth experience with DK2.

Better to run 3DMark and it will tell you if your PC is good enough - it will actually show you your system compared to recommended for the Oculus Rift.

Cyber, you should make new threat for CV1, this is a bit outdated already with pre-orders open...

Hey, guys! What i'd like to ask is if your PC is below the minimum requirements (the oculus tool says it is, although I own an ASUS ROG G751jy with GTX980M and i7-4710HQ), will it allow me to run the Oculus set or since it didn't pass the tool req it will stop me starting the games in VR mode?

It will run. And testing that system with 3DMark and you might get a 93-94% of what the recommended spec for the Oculus Rift says you need.

Laptops are NOT officially supported an may NOT work at all. I wish people would stop the confusion.

Great Tip 🙂
Recommend Score is 9271. My Score is 9319. Close, but I pass.

I hope that's not really the case, since my laptop seems powerful enough to run it. I know I would need to reduce some quality details, but banning all laptops seems not legit to me.

My score in 3D mark is 8436

Better to be confused than ignorant

Yes, I understand that you say that laptops are not supported because only a fraction of a fraction of laptops makes the cut. And by making this clear statement that laptops are not supported you will not be hit in the face when people start complaining about using $599 USD + taxes and shipping on a piece of brick they cannot use.

But, and I just ran these 3DMark tests tests on my Asus ROG G751JY:

Fire Strike 1.1


Sky Diver 1.0:


Cloud Gate 1.1:


Ice Store 1.2:


And though it doesn't clear the test completely I am certain that my laptop will be able to handle the Oculus Rift CV1 - to my satisfaction at least.

I'm really sorry, but you don't understand the situation. It's not just about performance (though that is certainly an issue as well). The main problem is that the GPU architectures used on the vast majority of laptops are fully INCOMPATIBLE with the Oculus software. Meaning the headset WILL NOT even be detected, let along work. The screen will remain black, you will never even see ONE pixel light up.

This is namely because of Optimus (aka Switchable Graphics) that causes the HDMI port to be hardwired to the Intel GPU. Even if you can overcome the compatibility issues, there is still a significant added latency from having to copy the back-buffer from the Nvidia card to the Intel card every single frame.

Maybe you haven't been looking at the forum, or choose to ignore all the warnings. Do a search for "Optimus", you will find literally HUNDREDS of people that are SOL because they tried to use the dev kits on their laptops. Literally, it just DOESN'T WORK.

The majority of laptops may be incompatible, but I don't think that's the case with ASUS ROG G751jy. The Intel video card isn't even present in the device manager, as this laptop uses the GTX980M only.
