FPS DROP

[RodoKiD]

Hello!

My big problem is with my new laptop. The first I got it, it had only dos system in it. Then my father took it to an computer "pro" and he installed windows 8.1 Pro, then put all the drivers on, but then I noticed, there was something wrong with the video card driver. My video card is Nvidia GeForce, but he installed Intel Graphics 4600.. I tought: "Fine, let it be." All my games ran fine. League of Legends with maximum graphics 100 fps. But then I tried to play Battlefield 3. First off, it said, that I don't have the right driver on my video card. Then I installed the right driver on my laptop from internet. Battlefield 3 ran, but with low fps and League was on 30 fps . I'll tell you all my specs too: 

Operating System:
Windows 8.1 Pro 64-bit
Processor:
Intel Core i5-4200M Processor (3 MB Cache, 2.5 GHz , 2 core, Haswell)
Ram:
4,00GB Single-Channel DDR3 @ 798MHz
Motherboard:
LENOVO VIUU4 (U3E1)
Graphics:
2048MB NVIDIA GeForce GT 740M
Storage:
931GB Seagate ST1000LM014-SSHD-8GB (SATA)

Thanks for helping, who can!

Did you download the driver for your gpu from Nvidia..?

GT740M is pretty bad, but, you should try again downloading the latest drivers from Nvidia.

Well uninstall the unused drivers like the intel one and re install the nvidia ones
