XPand Direct X 9

[andrerezende]

Hello folks,

There is much degradation on visual quality and FPS if RFactor 2 runs in a Windows XP/Direct X 9 system?

I doesn´t like the image quality on my system:
Windows XP 2 GB ram, CPU AMD Athlom 64 X2 Dua Core 5200+ 2.71 Ghz ,
Geforce GTS 450 1 GB

Is worth to change the SO to Windows 7?

No, that won't really make a difference. XP can use both your cores, and game performance between xp and 7 was often found to be nearly identical. I doubt rF2 is an exception to this.

I would suggest upgrading your RAM to 4GB or more and switching to Windows 7 x64.

The recommended system requirements are 4GB+ and a 64-bit OS.

Windows 7 is a pretty decent operating system. It may look like Vista on the outside but it very stable and seems to take a lot less of a machine than Vista did to be able to run properly. It's not as bare-bone as XP but it works very well anyway.

I don't believe that there would be an issue in regards to rFactor 2 running in XP. The only thing I may suggest would be that your system may be slightly out of date and your video card is struggling with the graphics.

This is a comparison between your videocard and mine:

I have to turn the detail down quite a bit just to get decent frame rate. I was thinking about upgrading my computer just because of this!

For what it's worth, these are my specs:

Windows 7 Professional
Intel e8500 Core 2 Duo 3 GHz overclocked to 3.83Ghz
AMD Radeon 6870 1GB
4GB DDR2 ram

Is this Niels Heusinkveld the physics guru?

The problem with XP is that even if you install 4GB RAM, it will only see and use 3GB.

Even though rF2 is a 32-bit executable, it can take advantage of 4GB+ RAM.

So that's why they recommend 4GB+ and 64-bit OS.

Don't know how to break this but a 5200+ paired with 2GB DDR2 and a GT450S represents a HUGE graphical bottleneck. Your GPU isn't just slowed by the processor, ram and almost certainly motherboard it's paired with, it's hamstrung by it. I'd be amazed if it's able to pull half the weight it can.

I agree. I have a GTX 460 and made the jump from an Intel Core2Duo 6850 to a Core i5 2500K and it woke the GTX 460 right up out of its sleep!

Another plug for W7, I found the nVidia drivers work better in W7 than they do in XP. I used to get all sorts of random CTD's and artifacts in XP(no amount of OS/driver re-installs seemed to clear it) but none of that in W7.

I agree with you.... its time to a real upgrade on my pc.

Thanks to everyone.
