Rejectthreshold VRAM Usage

Hi, I did a similar thread in the Monitor/GPU forum but as I know there are so many competent individuals on this forum I thought I'd make the thread here, I hope thats okay with the moderators.I have 2 questions:1. After having some initial problems with my RAM ive reinstalled FSX and am now in the process of applying tweaks. I've followed NickN's guide on nvidia inspector settings and also used bojotes fsx.cfg tweak (with some changes).Tweaks used:RejectThreshold=131072Highmemfix=1Texture_bandwidth_mult=40Texture_max_load=4096ForceVsyncfullscreen=1-||- windowed=0The rest is per the bojote tweak for a HT off 4.3ghz + CPU etc, but with affinitymask disabled.Frames in FSX are set to unlimited with anti_lag limiting FPS at 30When using the NGX at some test airports like UK2000 EGPH/ AS ENGM im never above 1400/1300MB VRAM but when at Aerosoft ESSA it goes up to 1522MB as maximum.Thats dangerously close to the max VRAM of my GTX 480, what can I do to get the usage down to a more "safe" level? I feel like if i continue running the settings as I have the right now I will run into OOM errors etc.FSX display settings are the recommended by NickN setup but with High 2x. Water and Autogen at Dense.Nvidia inspector settings are: 8xS AA, Transparency set to off/Multisampling, and AF 16x. I'd like to keep it like this because I don't like the tree shimmering on lower settings.2. In Ryans sticky it says to put transparency at 4xSupersampling, wouldn't this decrease performance?EDIT: I upped the Rejectthreshold to 256KB and also put Autogen back to VDense, but at ESSA the VRAM was now only about 1100MB, why is this?EDIT2: I have REX cumulus and cirrus clouds at 2048.Thanks in advance
