Freelancer Graphic Problems

[Eonaros]

Grettings everyone.

I'm having a problem with Freelancer.Every time I meet with 5-6 ships, it will lag, and I have to change the graphic performance in Freelancer itself.

Before in Discovery 4.85 , I had a 32 MB Graphic Card, and I could easily join a large scale battle ( Capital ships ) and participate in it with default Freelancer graphic performance.

When 4.86 was developed, I got myself a 64 MB Graphic Card and after I managed to join a battle, it just laggs, and I have to change the Freelancer graphic performance to 0.

My Current PC Specs:

Operating system: Microsoft Windows XP Proffesional
Processor: Intel® Celeron® CPU 2.40 GHz
Memory: 512 MB RAM
DirectX Version: DirectX 9.0c

Graphic Specs:

Name: NVIDIA Geforce4 MX 440 with AGP8X
Manufacturer: NVIDIA
Chip Type: Geforce4 MX 440 with AGP8X
DAC Type: Integrated RAMDAC
Approx. Total Memory: 64.0 MB
Current Display mode: 1024 x 768 ( 32 bit ) ( 60 Hz )
Monitor: Plug 'n Play Monitor

Everything else is good.

I hope you can help me.
Thanks in advance.
