Optimus igpu disable benefits?

My only question about that is then why does the bios specifically have a setting to enable or disable the igpu then?

It says in the bios three options for display mode, 1. igpu only 2. dgpu only 3. MShybrid. I haven't restarted and tried it so far though.

This is some tongfang variant, under the gateway name, but I have not figured out which one.

 

Agreed. OP should memorize the steps to switch it back, in case the internal display output is shut off. I doubt a budget model like that has a mux switch.

 

Ok well afaik the way to get back would be to use an external screen or from some online research, during post into the bios the bios screen might work regardless and just switch back to mshybrid mode.

From here in this thread looks like not much gain, but of course every system is different

Here's some nvidia speak but it's pretty general

Is there any way to check for a mux switch? I don't think there is a manual for this since it looks like it was a limited run for holiday sales.

 

You can just try it. If the internal screen goes dark, switch it back blind or using an external monitor.

 

Well from the first link I was actually going to test on msiab the usage of igpu during gaming, maybe if it's minimal it wouldn't be worth it. I just read the annoyance factors, ie no screen at all without lots of reinstall etc, in that first link and am wary now.

 

This.

If it was that easy then a lot of people would of done it years ago. The purpose of a MUX switch is to use the Dedicated GPU as the main display giving you full access of Nvidia's Control Panel like a desktop and unlocking the full ability of your GPU. There is no excuse for gaming laptops to not have a MUX switch these days. Personally i have optimus (Hybrid mode) turned on because i need the battery life as i use my laptop for work and other tasks more than gaming. There are some performance increase with it off but the major performance gains is with e-sports games like CS:GO, Overwatch and etc.

 

Well the reason I'm interested is the relatively weak cpu in this budget model, I always have mine plugged in it's not an on the go business machine etc Free perf bumps always preferred to spending money lol

Anyways so from this ncp screen I can infer no mux switch then?

 

From what you indicated earlier, you are MUX equipped:



If you haven't disabled the iGPU in BIOS, then the system will appear in the Nvidia Control Panel like a MUXless laptop. If you disable it in BIOS, the iGPU won't appear in the control panel.

 

Okay I'll have to try it and see then.

 

Upadate: Mux switch confirmed by a user in my thread in the other manufacturers section for this model. Thanks to @sfinney76
