Optimus - Unsupported Hardware

[l33t_supa_h4x90r]

So I have a laptop with Optimus technology, and I use the high-performance GPU, an Nvidia GT540M (2GB) to run RO. However, in the option, my GPU comes up as unsupported (although the memory is detected correctly) - and I am sure that this is what causes me to have much lower FPS than I should, since my laptop is capable of running much newer and more demanding games much better than it runs RO. Any help with this?

This is on my windows 7 installation by the way, not Linux.

That's weird.

Can you fetch the card's vendor and device id?

Go to "Device Manager" -> "Graphic card"

If you have an "Intel(R) HD graphics Family", that's the guilty.

Other games with "launcher" also suffers from this (Skyrim e.g)

Vendor ID for NVIDIA (which is the card's vendor) is 0x10DE.

Device ID should be 0x1050. However, on my device manager it appears to show 0x0DF4 as the device ID. Not sure if that's as it should be right now... But everything else on my computer seems to read the card fine...

(This is the point where I wish I wasn't an intermediate PC user.)

Hope you can make something out of this. If you need me to do or try anything, say so.

Just so you know, the Intel HD graphics also comes up unsupported. I'm assuming this is already known, and there is also a Linux problem thread on it? In case you ask, the vendor ID for that is 0x8086 (Intel Corp) and Device ID is 0x0116 (Intel HD Graphics 3000).

Optimus problem is on Linux. With Windows it should work. You need to force RO to use Nvidia GPU somehow. Maybe there is nvidia control panel or anything where you can say that.

I never used optimus laptop actually so i just guess...

Ieti, I have no problem with Optimus. It works fine for everything else and I know full well how to use it. The problem is with RO + Optimus. I have specified that ROlauncher.exe and ROClientGame.exe should both ALWAYS use the NVIDIA GPU (In fact, I've made it the default anyway, but I've also added a specific rule to be certain).

(I'll make a test to run RO on Linux using Bumblebee and see what that comes up with.)

EDIT: Ok, so I tested on my ArchLinux installation with Bumblebee and Nvidia driver 310.19 (which is just a bit older than 310.90 on my windows installation), and the GPU is detected properly by the launcher, as I remember it was back when I ran this game a few months ago on Linux. I will update this after I've ran it for a decent amount of time to post information on performance comparison.

Just say Ieti was right.

Just saying but no, he wasn't.

Bump. Game is becoming more unplayable every day for me.

I am running this on a brand new laptop on Ubuntu with UEFI and Optimus technology (Acer Aspire V5 571G), using Bumblebee to switch cards.

I have found that with Bumblebee, I have to switch cards in terminal using

$cd Regnum/
$optirun bash
$./rolauncher

The game runs quite well, the card is an Nvidia GeForce 620M 1GB, and I can get about 40FPS with graphics set to "high".
