Battlefield 4 - Huge FPS Boost FIX TWEAK

Dogtag taken

In order to play Battlefield 4 on low-end computers including mid range business laptops is reduce shadow map resolution witch is biggest performance hitter.

To reduce shadow map resolution you have to do it in-game, no ini file editing in this case is not possible, just launch game in "test range" mode hit console key (under Escape) and enter following command into console and determine value (256 is default value); example:

WorldRender.SpotLightShadowmapResolution 128

 

Game restart is required to make changes take effect

 

Alternatively you can create user.cfg file (not recommended) into your root Battlefield folder (C:\Program Files (x86)\Origin Games\Battlefield 4) and paste these already tested performance settings with lowered values into it and run game with more fluent graphics.
