Would this be a good card for Prepar3d v2? Its 3gb so has heaps of vram.

 

Someone has offered me this card for a good price, I know it will be a good upgrade form my current HD 7770. I would have preferred the 680 but just to give you an idea I can get this very good condition 580 3gb for HALF the price of a used 680 2gb.

 

should I go for it?

I have two GTX 580 in SLI. I havent had any OOM problem with my setup. On the other hand, I'm more a GA flyer than heavy tubeliner and I dont use heavy airport sceneries so my system is certainly less stressed than some other enthousiast on the forum.

 

But overall this is a good choice if you intend to use it on one screen only. My setup is in surround and I'm thinking of upgrading to a faster card as the performance on 3 screens are low on FPS when flying in heavy volumetric cloud. Performance on one screen are very good.

Sounds like a nice upgrade. Running 6 cores @ 4.5 would go well with the 580.

The ram increase will help also.

It really depends on how much you can get the 580 for.

Thanks guys,

 

i went ahead and got the card. got a good deal.

 

The improvement was very noticeable, the AA and the smoothness of the shapes was really a ten fold improvement. I went ahead and delete my cfg file and let it rebuild. unfortunately that set me back a bit. so I am back to tweaking to get it looking nice.  I am going to wait for the 2.1 patch though because no doubt that will change a few things.

 

I still have an issue though, had it in FSX aswell and have never been able to shake it. When I fly straight and level everything looks great and runs smooth. however when I start making a turn, the ground becomes blurry and the frames seem to jitter a lot. I don't believe its actually a performance issue. I think its maybe a screen refresh issue? I have the same thing on two different monitors. Its not a huge issue, but it is noticeable. Turning all the setting hard left still has the issue. thats why I don't think its performance. Any ideas would be great, do I need to look at the half refresh rate fix?

Try getting ride of all trace of the old 7770 drivers with a registry cleaner like CCleaner.

Delete the Shaders folder at:    Users/your name/AppData/Local/Lockheed Martin/Prepar3D v2/

 

Might help.
