While I'm satisfied with the Asus HD7870 with Catalyst for most of the flights, it has a problem with heavy overcast clouds. A lot of stuttering especially taxis in turns and some stuttering climbing to altitude in and around the clouds. Clear days pose no problems. A minor stutter here and there but nothing major. I have tried everything I can think of the alleviate this annoying problem. REX cloud textures are at 1024x1024. I have also tried the HDEv2 textures. Same results.

 

I've been reading that the AMD cards may or may not have a problem with clouds in FSX. I can normally figure this stuff out but I need to ask for opinions on a replacement graphic card or opinions on this stuttering problem.

 

The card I am looking at to replace the HD7870 is the Asus GTX670-DC2-2GD5 GeForce GTX 670 2GB 256-bit GDDR5 PCI Express 2.0x16 HDCP Ready. 

I'm ok replacing the card if need be but if anyone has any ideas or suggestions, they would be appreciated.

 

Thanks

 

Those 2 gig cards wont cut it need at least 4gig and even then you can get stutters think about a 4 gig card or you are wasting your money been there done

that.

What am I missing. I have a 1.5g 580 and dont have any problems with stutters in any weather condition including traffic. I have never seen the GPS use more than 1/2 the memory. Now , very high resolutions and multimonitors, perhaps

I think you two may have solved my problem. I have two monitors. One for the 2D and the VC. The other is strictly used for instrumentation. My ole eyes are not what they used to be and it's easier for me to see the avionics on a separate monitor. I also just made a test flight out of FSDreamteams KDFW (high graphics) and a lot of rain and clouds. The FPS was abysmal. I noticed the further away from all the graphics, the FPS picked and by the time I reached Florida, (no rain or clouds and a standard FSX airport) it was maxed at the limit of 30.

 

I'm thinking the 4 GB GTX 670 instead of the 2GB might do the trick. The price difference is minuscule. Does this sound feasable?

 

Thanks

"4 GB GTX 670" Smart choice go for it.
