-While a graphics card is rendering, it cannot redraw the user interface, which makes Blender unresponsive.
+On older GPU generations, graphics cards can only either render or draw the user interface.
-We attempt to avoid this problem by giving back control over to the GPU as often as possible,
+This can make Blender unresponsive while it is rendering.
-but a completely smooth interaction cannot be guaranteed, especially on heavy scenes.
+Heavy scenes can also make Blender unresponsive on newer GPUs,

-though we might be able to improve this somewhat in the future.
 
-If possible, it is best to install more than one GPU,
