Aperrently Acer locked most of the Advanced setting away. I tryed to check if hypertreading was enabled and enable memmory remapping but under the Advanced Settings are only a enable Intel-VTX and Intel VTD.
Does someone know how I could get acces to the desired settings?

Most laptops have pretty locked down bios, its unlikely you would have access to those types of settings

#

You can see if HT is enabled in windows

Ah okay, thank you.

#

do you have pictures of the bios?
laptop BIOS often put things in other categories than their desktop counterparts

#

and with "in advanced Settings is only XY" did you mean literally only? Or just relevant only

#

many laptop manufacturers also rename stuff in the BIOS and it's harder to recognize what it actually does (for example "intel rapid storage" might be named "intelligent disks" or whatever

With only I mean littarly only two entries.

uhhh huh.... For nitro laptops I actually expected some kind of click-bios at least... does not look like you have many options tho

#

also...

#

this is pretty hilarious

#

those are the virtualization options you're looking for tho.

#

or do you mean ReBAR with "memory remapping"?

I think it's ReBAR. Yes it is. Apparently its also sometimes called "Smart Acces Memory". I was trying to follow a guide to optimise my system for anything Gameing basically but mostly to get the most out of Spaceengineers. The reason I wanted to check is because something strange is going on there its stuck on 30-FPS and 200% CPU usage. Empty new world or star system with over 50 grids and 50+ mods as comparison both low and ultra settings. While I can play a heavy moded Skyrim. AC Unity, Helldivers, Warhammer Totalwar 3 all on Ultra settings and have 120 fps.

#

how are you measuring those values?
do you have information about 99th percentile FPS?

#

reBAR is also not available on all systems, for example the "Smart access memory" feature from AMD (basically ReBAR rebrand) only works on Ryzen 3000+ with Radeon 6000+ systems

#

you might also need a BIOS update

#

The game internal functions for it.

#

Btw. Sehe grade du kommst auch aus Deutschland xD

#

should've probably googled earlier - those GPUs (and the motherboard chipset) DEFINITELY don't support ReBAR - they're far too old and laptop BIOSes mostly don't get feature-updates anyway

#

#

ReBAR came out in 2021
