This is an issue just with Amelilas mods, mainly because his mods are huge (mainly talking about jeuno, gusta and reisen).
Turn bump mapping off, bump mapping requires a lot of extra textures to be loaded (textures that control the bump mapping system, you can't see them). If you turn it off they aren't loaded and it saves ram. The problem isn't how much ram you have, it's how much ram ffxi is capped at using.
Amelilas textures are visually great but his mods are way too big and seem to be getting bigger with every release. If you still have problems with his mods after turning off bump mapping I can make smaller versions of them to fix it.
That's your graphics drivers not liking something FFXI is doing. Assuming you have dgVodoo, do you also have ReShade? Does this appear on every instance or only when your running your own party? Also what kind of graphics card do you have and what is the resolution for each of your instances?
Kireek - I will double check to see if my bump mapping is on or off when I get home. I just turned dgvoodoo back on as I just built a new pc. I didnt have the issues with the last one I was using whatsoever. I attributed it to being a new gpu not liking it. I will certainly give that a shot.
Saevel, it's very strange. it doesnt happen everytime, sometimes I have no issues at all. I could load all 4 or 5 characters with no issues but every like 15th or 20th time it just gives me the middle finger. My buddy was having the same issue and I just assumed it just a glitch. It only happens in the larger zones like lower jeuno or reisen. I am now using a RTX 2080ti and I just turned dgvoodoo back on last night and i have reshade but haven't messed with it. All instances are running full screen 2560x1440. I didn't think that would be a problem since I was able to run the same characters on my laptop and didnt have this issue. The card in that is the AMD equivalant of the GTX 1050. I cant recall the name off the top of my head.
I will give the bump mapping a try and make sure I have dgvoodoo set correctly and go from there.
Thanks for the assist! Keep you posted if there continues to be issues.
