High/Low resolution graphics slider in game settings

So after introducing new high res graphics in the Air Sweeper update, in the latest patch SC has drastically reduced the resolution of game graphics. Only buildings/walls/troops/scenery/background seem to have been affected, the game UI buttons are all still sharp. This has presumably been done to reduce lagging on older devices.

What I am requesting is a switch/slider in game settings to allow players to switch between high/low resolution graphics. This allows players with high spec devices to enjoy high res graphics, while players with older devices can play without lag.

This ought not to be too difficult to implement, and the game looks terrible at the moment.

Let me know what you think! :)
