Nvidia Optimus- GPU switching problem

Same problem, MSI FX600 with a GT325m

Tried using latest drivers from Nvidia and Intel sites to no avail, so tried updating from MSI support, still nothing...

Trying to run Eve online (a bad game) they have a partnership with Nvidia for developing their new graphics engine so i dont think its a lack of cooperation between the two companies that is causing the problem (although it would be hilarious if that was the case)

Ive got a petition up with MSI support but not expecting much help

When it messes up, the only way I know that solves it is reinstalling Windows, changing drivers doesn't work.. The problem lays only in changing gpu engine, it likes to crash from time to time.. I believe turning off updates helps a bit. On the other side, when it works, it works on almost all driver version, up from 256.67, or something..

Same issue here also

MSI FX600
325m

Half my games don't switch even after enabling them in the profile of the Nivea control panel. Tried all sorts to resolve this no luck so far.

Reporting back regards MSI FX600

I uninstalled all instances of Nvidia drivers and Intel drivers and used driver sweeper to clean off any remains.

I then installed drivers from MSI support website page.


This RESOLVED my issues with Test Drive Unlimited 2 not switching with Optimus it's also solved some other game issues.

My main problem now is that MSI drivers are quite dated although I have started a thread on the MSI forum about that.

Hope this helps, optimus can be a shocking experience for gaming I wish they added an advanced bios feature to disable intel gma hd and Optimus all together and default to Nvidia as main card.

I've the same problem with my Asus N53 SV. From one day to the next, World of Tanks dont work with my NVidia 540M, but other games does .....nothing worked, so I'll try your last option before a SO format

This is a very important problem, ....nothing works !!

I stopped using the MSI FX600 laptop i have now for any gaming because the whole experience is spoilt because of shoddy graphics switching on newer games and older games.

Installing Nvidias own drivers just causes more issues because MSI do something to them to make the switching work properly.

Think i'll be keeping the laptop as a laptop and looking at a small shuttle pc that will take a large card for some on the side gaming.

Hi everybody,

I have exactly the same problem, but I'm not willing to throw this laptop away when it comes to gaming.

This is my setup:
Dell XPS 17 laptop with Nvidia Optimus technology (integrated Intel GPU für standard apps, extra Nvidia GT 555M GPU for games)
Windows 7 Home Premium 64 bit w/ latest updates

No matter which Nvidia driver I use (latest version from Dell homepage, or latest version from Nvidia homepage), the problem stays the same:
Even if games are setup to use the high performance Nvidia GPU in the Nvidia Controlpanel, games use the slow Intel GPU. (as shown by the GPU indicator tool)

I don't want to give up on this, because this Dell laptop simply was too expensive to just use it as an office machine. And it'lll make my wife cry if I won't get Civilization and Portal to run properly again!


Any help, hints, ideas are greatly appreciated!

I've got an Asus with a 2gb card in it (GT-630M) but games would always run the intel chip, even after explicitly telling them not to in the Nvidia individual game settings. Anyway was just fiddling about and noticed the option in Manage 3d settings\settings of Multi-Display/mixed-GPU acceleration, it was set for multi display performance mode and I switched it to single, tried awesomenauts and black ops which both used to run the intel and both now run the Nvidia, haven't tried it plugged into my tv with hdmi out yet, just on the laptops own screen, maybe i'd have to switch it back when I do that. Hope this helps :)
