com_AllowConsole 1
com_SkipIntroVideo 1

These two just allow the console to work and skips the logo videos.
vt_qualityhdplossless 1
vt_qualityhdppower 0
vt_qualityhdpspecular 0
vt_qualityhdpnormal 0
vt_qualityhdpdiffuse 0
vt_qualitydctpower 100
vt_qualitydctspecular 100
vt_qualitydctnormal 100
vt_qualitydctchroma 100
vt_qualitydctluma 100
These set overall quality level, lower on the HDP and higher (percentage) on the DCT with lossless support. (However the textures are what they are so you can’t expect miracles.)
vt_usecudatranscode 2
This is the CUDA function but 2 enables all of it not just smart mode.
vt_maxppf 1024
vt_maxlockedpages 256
These are what I’m struggling with now, a value of 2048 and 1024 respectively will cut down texture streaming to less than a second but will also cause possible glitches and stability problems so I’m testing various compromises here.(This is the number of paged\cached megatexture pages or what to call them.)
vt_pageimagesizeuniquediffuseonly2 8192
vt_pageimagesizeuniquediffuseonly 8192
vt_pageimagesizeunique 8192
vt_pageimagesizevmtr 8192
This is max texture resolution, again the textures are what they are and you can not get them to be better than that other than with some small tricks.
vt_minlod -1
Slightly negative LOD for a sharper image
vt_uncompressedvmtr 1
vt_uncompressedphysicalimages 1
vt_vmtrcompression none
Use uncompressed data (If available, it’s not.) instead of compressed and compression method. (Tab two times will cycle compression levels, that’s also how I found the CUDA = 2 thing.)
vt_maxaniso 16
Tell the megatextures to use full 16x AF filtering instead of 2x, sharper unless forced via CCC / NVCP already.
vt_restart
Change anything with the virtual textures / vt and you’ll need to restart them, best is to execute the config (exec rageconfig.cfg for example.) in the main menu.
More Tips:

PC gamers who want to change FOV, all they need to do is add "+cvaradd g_fov 20" command to RAGE's launch option. By adding this players are telling the game to run at its default FOV that is increased by 20 degrees. The default FOV is 80, and so if player add 20, they will get a FOV of 100. Players can lower the number to find their sweet spot.

In addition to this, players can edit "render_controls.xml" file, which is located at "C:\Users\[username]\AppData\Local\LAG\data\settings" folder. By editing this file, players can easily turn on and off SSAO, Depth of Field, and other graphical options with simple "TRUE/FALSE" value.

прописывать их \Rage\base\rageconfig.cfg файл создавать самому

Создаем rageconfig.cfg в Rage/base/ и добавляем следующее:





Обратите внимание, что у всех конфигов видеопамять 1024мб стоит.
И после // удалить не забудьте.

После этого прописать в консоли(~): vt_maxPPF 16.
