Hey.
I have some problems with GTA V... Sorry for my english.

First problem.

Can someone explain me this?
I tried to disable integrated CPU graphics (Intel HD 4400) and the result was I had 15-20 fps less in GTA V. How is this possible? I have MSI R9 270x HAWK (Overclocked) with Intel Core i3-4130. This is really weird...

Second problem.
I have an issue with performance. I have about 45 fps and when i drive/fly fast it drops to 30 fps.
I have about only 5 fps more if I change graphics settings to lowest. And if I change the game resolution I have the same fps as before. And yeah, I've got 15.5 drivers. (I have DirectX 11, MSAA,FXAA,VSYNC off.)

My PC:
CPU: Intel Core i3-4130 3,4Ghz
CPU Cooler: Gelid Tranquillo Rev. 3
GPU: MSI R9 270x HAWK 2G
RAM: Geil EVO Leggera 4gb (2x)
MB: Gigabyte GA-B85M-D3H (rev. 1)
HDD#1: Seagate Baracuda 7200.14 (1000gb)
PSU: Seasonic Energy Knight SS-500ET
OS: Windows 8.1 64-bit

Thanks for reply.
