Hello peoples!! Today I bought witcher 3 which I was so excited was, it sucessflully installed but the bad part is that I get like 5 or 6 fps, I minimized those graphics and all and now 10 fps would be maximum.. Please help me fixing it, I wanna make some YouTube videos..

Without any information at all concerning your hardware specification, I hardly believe that anyone here will be able to help you. With that being said I doubt that you'll be able to properly make youtube videos with a pc that is only able to run w3 at 10fps. I also assume that you should upgrade your gpu.

Please tell me the specs a gaming PC must have..

Just google minimum requirements for witcher 3.

The minimum requirements for TW3 are:

OS: Windows 7 64-bit or Windows 8 (8.1) 64-bit
Processor: Intel Core i5-2500K 3.3 GHz or AMD CPU Phenom II X4 940
Memory: 6 GB RAM
Graphics GPU: Nvidia GeForce GTX 660 / AMD GPU Radeon HD 7870
DirectX: 11
Hard Drive: 35 GB of available space

Note that only "full size desktop graphic cards" are supported.

I've 8gb ram and 2 GB graphic card..

So? Name your graphics card and PC processor.

Didn't try this myself but some people say ultra-low graphics mod may help. I think that's the one
