F irst of all i want to type down my system specs down:
It is an ASUS laptop
Intel CORE i3 5005U @ 2GHZ
RAM DDR3 4 GB
Graphic Card one is onboard card i think and other one is NVIDIA GEforce 920m 2gbram
System is running on windows 10.
It is a new laptop and i havent downloaded new drivers for graphics and also i am not sure if new driver would be good since sometimes old games may have problems with them.
My problem is i am having unusual fps drops from time to time especially in 1 WB vs another one but suprisingly this changes depending on the maps.Scenarios are nice got no problem.
And i am trying to listen advices and changing it to windowed fullscreen and when i for example press ALT+ENTER to make it full again i get graphical glitches like my characters skin gets funky colours ,missing limbs or head (creepy).
I also want to know what should i exactly choose i n NVIDIA control PANEL.Like the option multiple display mode/single display mode and other minor details in the panel because in there for example there is an option for getting benefits from multiple cores and someone told me this game is old and does not benefit from multiple cores etc... so what to do ? Would be so kind to tell me what to pick from NVIDIA CONTROL panel aswell ? I am willing to send screenies JUST help me with this problem cause i really enjoy this server the game and the athmossphere and as a WITCH HUNTER i need smooth gameplay more than anyone else i guess.
I disabled every addon.And i would love to know what to do with that option in video part of the game GPU CACHE MEMORY bar(to the left ? to the right ? middle?) Also there is a box with shader performance bla bla in the video menu aswell.
Also when i go windowed i do not know if i get performance increase of place but the games color scheme changes like it gets brighter in fullscreen etc. Anyways if you are an expert and help me i will be so happy

(i wasnt using windows 10 until last month and i heard it has really bad applications which are running background and i tried to disable them but i am not sure if i did everything in the name of tweaking it so advices welcome if you are sure.)
I am sure out there people who can benefit from this thanks in advance !
(PS:I APPLIED 4gb patch to W AR.EXE someone told me to use it since warhammer is not getting benefits from 4GB ram etc..)
