Intel Graphics HD 4000 & nVidia Optimus = DCP Latency issue

I've got a HP Pavilion dv6 7090el, which runs on a 3rd gen i7 ,8 GB RAM and a nVidia GeForce GT630M and win7 x64.

I've ditched my old desktop pc just a few days ago which had connected my external soundcard to move all my stuff on the laptop because it's way more powerful than my old desktop, only to find out that because of the Intel 4000, the DCP Latency becomes unbearable and i've got continuous audio dropouts which are quite frustrating when you're working with audio and such. Be aware that i'm not using it professionally, that's why i've decided to move everything to the laptop, but it's still darn annoying. Looking for what was causing the huge lag, LatencyMon showed it was something called ACPI.sys and that i had to disable in the DM a Microsoft ACPI battery compliant something. Did it but no change whatsoever, i therefore started to disable everything one by one to find out it's the Intel 4000. I've read around the internet that it's a common issue but i wasn't able to understand if it's a bypassable issue. When i'm home i connect the laptop to an external monitor and if i disable the intel 4000, win switches to the "default graphic mode" or somthing similar, and when connected to the external monitor it still doesn't allow me to reach maximum resolution, but instead stops at the max res achievable on my laptop screen(1366x768). I use no graphics at all so it would be even fine for me to run on the default module if only i could get it to output at a higher res.. cause a 1366x768 on a 1920x768 24" it's just silly.

Is there a way, that even requires hardware modification, to bring out the output of the GPU so i can bypass this damn Optimus/Intel 4000 problem?

Bear in mind that English it's not my first language and that i'm no good at writing a decent report.. just fiddling with knobs and such, so if you need more information, just ask. Thanks!

Please provide the full model of the hardware that you are using such as the sound card, laptop and other hardware being used relevant to this issue.

Additionally post the dxdiag report from the system you have issue with.

Include any driver versions for the hardware involved on this behavior.

The laptop is a HP Pavilion dv6 7090el, which features:

- CPU: Intel Core i7 3610QM

- Intel HD Graphics 4000, driver version: 8.15.10.2712 (on the driver download page, it says there is a newer one available (15.31.17.64.3257, released the 2nd of August) but when i try to install it, it says that (literally, from italian) "it's not validated for the pc in use"

- Motherboard: HP 181B

- GPU: nVidia GeForce GT 630M

- 8 GB RAM

- Internal Soundcard according to the device manager should be a IDT HD Audio CODEC, i actually don't know how to look this up properly.

-External Soundcard is a Traktor Kontrol S4, which uses a Traktor Audio 10, as far as i know. One problem that already exists is that i can only plug it in the one and only USB 2.0 port, because on the other 3 USB 3.0 ports it gives blue screen and it's been a known bug yet to be fixed. Driver for this one is up-to-date(3.1.0, firmware version: 15)

However yesterday i had an idea: since LatencyMon showed that the process causing the DPC lag spikes was ACPI.sys, the internet suggested disabling the ACPI Microsoft.compliant battery something, however that didn't do the trick for me, but gave me an idea: what if the HD 4000 was sucking out too much power? So i set it to low power consumption(the 4000 only, via its own control panel, not the windows one) and i'm not sure if i rebooted or not, but shortly after DPClat showed that everything was fine, with avg latency of 200us. However today it's giving trouble yet again and it still is set on low power consumption..

ACPI.sys controls how your operating system manages the power settings. Being this a laptop system with switchable graphics (Intel/nVidia*) this might cause this service to be constantly monitoring in order to effectively switch between one GPU or the other.

You could try checking with your Original Equipment Manufacturer (Hewlett Packard*) for a way to disable the Intel(R) video controller or disable the third party video controller, basically, test disabling switchable graphics. Also test disabling any power savings features and use the system in full power (this through the BIOS and operating system settings, check with your Original Equipment Manufacturer on this).

Please post the dxdiag report from your system if the issue persists.

Additionally, please check the driver version for the nVidia* GeForce GT 630M controller.

The reason I ask for this, is because I cannot find a newer version than 9.18.13.614 for your system, but in the dxdiag report I see that a 9.18.0013.1100 version is installed. Please check with Hewlett Packard* to see if this is compatible for your system. If it is, then you can try using our latest generic driver.

Also be sure to install the latest BIOS for your system, once you update it, then please let me know the BIOS version installed.

To install our generic driver, please follow the instructions on this article:
