SLI Users Only - Temporary Solution to reduce Artifacts

[Skywolf 992]

Hey to all SLI users Only,

 

Below is a list of files which need to moved away or renamed etc (extension changed) in order to minimize SLI artifacts.  Readers this post only Applies to NVIDIA SLI users of Latest P3D v2.5+ (2.5.12945.0 / 2.5.12946.0 HF4) with latest Nvidia Drivers (353.30) which have Prepar3d profile, as this is does NOT affect Single gpu users at all.

 

For my research only: While I was playing with these files, I did notice that SLI is rendering some the bmp files in a different way - I was changing the bmp in these files, and sometimes the effects just worked.  If the graphics experts in this forums who have experience with DXT 5 and extended bitmaps - take a look at them.  Easy place to start is looking into the fx_vaportrail_l.fx, fx_vaportrail_r.fx files - they provide excellent trails with P3D's default flight with the raptor.  Just load that flight and take off fast, and look in external view - all those lines, but then again it works fine in single gpu environments.

 

Anyway for SLI users, just zip these files and that way for the time being you will get flights with very minimal artifacts with SLI.  Remember to apply these files back if a new update comes.  This is a very temporary short gap measure for the time being only.  Either LM will get it fixed or Nvidia's newer upcoming drivers etc.

PS - Rob can you let the LM team know about this.  Might help to look exactly here instead of browsing everywhere in effects and effects/textures directories
