usual symptom na gamay ra imong video memory to the resolution that you're running is when you're playing a 3D game and you alt + tab to windows, the graphics card has to render another image which is your desktop from the current one na 3D game. if gamay ra imong memory, it will take time for the graphics card to show your desktop whereas if sufficient ang memory, dali ra ma render ang imong desktop.
