Something wrong with my graphics

[StephenMB]

So my system is a beast. 64 megs ram, 12 core, nvidia titan x pascal, yadda yadda. I can run 18 instances of EQ2 on this system at medium reso and EQ2 is very graphic intensive. I run 5 windows in WoW BFA. Full screen on my main and then 4 on other screen. If I set everything to 1, then go back to my main one and increase those settings to say like 7, the 4 set to 1 lag or slideshow noticeably. Not horrible but bad enough to impact gameplay. This absolutely should not be happening. My friend who’s system is significantly inferior can run his 4 on one screen at like 5 and his main on 10 with zero lag or slideshow.

I do fresh boots.
No background programs running (that I know of)
my graphics card is set to use the settings of the game graphics settings.

but again, if something were wrong I wouldn’t be able to run 18 instances of EQ2 without a hitch or ANY lag.

since I am brand new to WoW. What could I be missing? I use isboxer and it sets frame rates (I think). Could it be direct x setting since they have 3 different ones? I just don’t know. Help! The whole point in spending that much on a system is for running ultra quality!!
