I have an Inspiron 15 i15RV-954BLK laptop with an i5 processor, 4GB of RAM, and an HD 4000 graphics card. I can play games like Minecraft and operate recording software with relative ease. However, with games like Skyrim, Batman: Arkham City, and Mortal Kombat Komplete Edition. I can not operate both without extreme lag and framerate drop. In addition, Mortal Kombat, even when set on low quality, is laggy and slow, even when operating alone. I have looked into various remedies to this problem but still am not sure what to do. Will a simple RAM upgrade solve this? Is it even possible to upgrade my laptop? Help!
