Lag every 3 seconds

[Eonaros]

Hi

I have:

Packard Bell EasyNote TE69KB

AMD Dual-Core E1-2500 1.4 GHz x64
4 GB DDR3 RAM ( 3.44 Usable )
AMD Radeon HD 8240 512 MB GPU
15.6" HD LED LCD at 1366x768
Windows 8 64-bit

I got this few months ago, and I was very happy knowing I can play FL again lagless.

It can run Battlefield 2 , Euro Truck Simulator 1 and Halo 2 no problem.But Freelancer does have problems.

I am able to run FL at default screen resolution, which is 1366x768.( I launch FL via Discovery Launchpad )

When I play, FPS is always 60, at some parts goes down to 40.So, when I am flying, everything is perfect except that every 3-4 seconds, the entire game skips a moment, and continues normally afterwards.That normality lasts for 3-4 seconds until it happens again.A lag spike, so to say.

I had similiar problem with Halo 2, but I solved it by runing it in compatiblity mode for Windows Vista.

I tried to run FL in all kinds of compatibility modes, and even as administrator, but that doesn't help.

Making the resolution smaller, doesn't help.I will try to make a video of this.

Any solutions ?
