Right click on the game, go to properties, and copy+paste this into your launch options:

+set g_fov 100 +vt_maxPPF 32 +image_lodbias -0.5 +cvaradd m_menu_sensitivity -0.20 +cvaradd r_UseDynamicEnvironment -1 +com_skipIntroVideo 1 +image_anisotrophy 16 +image_use

Next, navigate to C:\Users\UserName\AppData\Local\ and create a folder called "id software" if it doesn't already exist. Within that folder, make another folder and call it "rage". This folder will act as the game's cache and should reduce saving and loading times, which will otherwise get progressively longer the more you play. These folders *may* already exist if you are on an earlier release of W10 or W7/8.1.

The above will auto-skip intro videos, increase the default FOV of 70 to 100, virtually get rid of texture pop-in, significantly reduce the mouse acceleration in menus, make the game look slightly better, and improve performance.

Untested on AMD cards, which always hated this engine anyway. Also untested on Intel iGPUs and GPUs but I suspect you'll have more luck, since RAGE was optimised for integrated graphics. Tested *extensively* on almost all modern Nvidia GPUs. Ideally you also need a 900-series card or better (or a 750Ti, which uses the 900-series architecture) so that you can use more modern drivers/GPU technology. If you have an older card, I recommend that you use an older guide, although the above launch options will still have positive effects. You can suggest additions in the comments and I will likely integrate improvements into the guide.

The next step is optional, but if you want less compressed textures and have 4GB or more VRAM, then do the below also:

Open up notepad (or a text editor of your choice) and paste the following in:

seta image_usecompression "0"
seta image_anisotropy "16"
seta vt_pageimagesizeuniquediffuseonly2 "16384"
seta vt_pageimagesizeuniquediffuseonly "16384"
seta vt_pageimagesizeunique "16384"
seta vt_pageimagesizevmtr "16384"
seta vt_maxppf "24"
seta vt_maxlockedpages "256"
seta vt_minlod "-2"
seta vt_lodBias "-2"
seta vt_maxaniso "2"
seta vt_qualityhdplossless "1"
seta vt_qualityhdppower "0"
seta vt_qualityhdpspecular "0"
seta vt_qualityhdpnormal "0"
seta vt_qualityhdpdiffuse "0"
seta vt_qualitydctpower "100"
seta vt_qualitydctspecular "100"
seta vt_qualitydctnormal "100"
seta vt_qualitydctchroma "100"
seta vt_qualitydctluma "100"
seta vt_restart

Save as rageconfig.cfg in steamapps/Rage/base. Click "replace" if it already exists. This file reduces the texture compression with a negligible hit to performance.
