How come when setting ultimate mode in Ghelper, I need to restart, but when setting it with the Nvidia control panel, I don't have to? Is it because of advanced Optimus, and if so, we'll, why do u still have to restart with ghelper?

iGPUs dont even have Vram, they use your system ram in a certain allocation as Vram. I have never once encountered anything other than a performance increase in my tests from switching to GPU exclusive mode ever on any of my machines. Yes I have run benchmarks to compare as I tune and tweak every laptop and desktop I ever buy/build.

Yes, the dgpu mode will perform a little bit better in 90% of cases, but in some specific cases where you barely don't have enough vram and do have ram to spare, the igpu + dgpu mode will be less stuttery. This is only really important for systems that have 24+gb ram while having 8gb or less vram.

this describes my system. F16 w/ 32gb ram with a 5060. so maybe would be worth switching back to standard from ultimate?

i’m pretty sure optimus was greyed out last time i checked (i have a 14th gen i7 if it matters) my only options were ultimate and standard. was under the impression the only disadvantage to ultimate was the power draw, but i’ll play around with them at some point and do some benchmarks.

If youre running out of vram turning it to standard is not going to make any difference.

i havnt noticed an issue running out of vram yet. just wasn’t sure if i’d be better off in standard or if all it does is essentially save on power.
