Physx?
« on: December 27, 2010, 17:00:37 »
Is this really needed to play the game, even though i have a 8.0 GB ram and a Graphics Chipset   ATI Mobility Radeon HD 5470? And wont it cause compability problems since i do not have anything that is called "nvidia" as hardware? o.o

It's not needed, but it makes the game run smoother if you have it.

I have a decent machine, runs everything super smooth except extremes. Because? I have an ATI card. I have not played this game more than 3-4 hrs since release because I dont find its performance on my ATI machine acceptable. I had it first week of release.

Hi itg172,

I doubt that PhysX has anything to do with your problem. According to the scant information from the developers, PhysX is used only for the physics routines for ship dynamics, etc., and only the version that runs on the CPU. Apparently nothing of PhysX is used that is specific to nvidia GPUs.
I, along with many others, get good performance with ATI graphics cards—an HD 5850 in my case.

There are many reasons for poor performance that are not related to the graphics card. SSE differs from most other games in the large amount of processing that must be done by the CPU before each frame can be rendered.

Regards,
Marty

Well it appears then we have conflicting information.

My tech support request week 1 was never responded to either  :thumbs:

So, I've yet to feel like this program has given me my investment.

In the first link, read the post by silicondoc near the bottom for a summary of the relevance of this ancient topic.

The second link is not relevant because it requires that you also have an nvidia card installed.
As I explained, so far as I know, SSE does not use PhysX for its rendering enhancements—only for its CPU version of the physics routines.
You might ask VSTEP for a clarification of this issue.
