Valve is in the update mania and has now already announced the next changes for the game. With the upcoming patch a graphic mode is supposed to come, which should relieve the RAM.
After big updates on grenades and other community requests, the Counter-Strike developer sends out the next small update. This time it’s about an extra texture/video mode, which should pre-buffer good textures until they have to be rendered. This should save workload in the RAM area.
In the CS:GO blog the pre-release notes were published. Besides the “Texture Streaming” there are some small changes in the process of texture calculation.
Currently the update only comes for the Beta Depot and is not integrated in the real game.
