Savage not newbie friendly

[mutan]

I remember long time ago i had to set gfx_allVBO to 1 manually to get all the shiny graphic features (seems to be fine now with new install tho). Now after fresh install i'm having weird game lag spikes (not net) hitting performance overlook (my friend said to me that this game is not for his PC due to this, and he have good machine). The semi solution to this is host_maxfps 1000 (default is 130) but the lag is still there sometimes. Also there should be warning that new install in existing Savage XR folder will delete ALL Savage XR files, configs, maps, overhead templates and everything.  

FIXED: Weird but this gfx lag was caused by enabled sun. Even without any custom NVIDIA settings.

It does not delete anything, just overwrites the default files (configs, textures etc). NOT custom stuff that's not in the official distro, like maps or presets.

Sorry but I must dissagre, I have chosen folder with existing Savage and it completly deleted that folder and then installed in to it. Lost my demos, screenshots and everything else. I have windows 7.

And about that lag, demo shows that it's not always there and it's not internet connection related:

Lag is there when i look at SH/Lair and newest gfx drivers didnt help.

Also when I turn Optimizations in System menu I see squares on world textures, like teir3 textures are being disabled or something, weird.
