Strange Error

[XunTzu]

When viewing certain areas of the worldspace, in a specific camera direction, my FPS plummets, script latency skyrockets (to the thousands of miliseconds) and if I let the camera linger on the area, lighting goes to hell too, flashing between dark, light, and superbright.
 

Usually the area I'm viewing has had no previous issues.  I have no problems with interiors.

 

Had recently increased my uGridstoLoad, but I don't think that's the issue.

edit: so for whatever reason, it's not lagging that crazy anymore. had just installed new driver and it disabled my SLI.  Re-enabling to see if it hurts.

 

Edit 2:  Getting problem in Riften now, can't even load up the game.  Anyone advise?

[XunTzu]

Nobody has any ideas?

I'm not sure how the ENB treats VRAM in SLI. It's possible that it's only seeing 1GB which could mean the engine is simply running out of space.

 

Are you using ENBSeries v0.262? Note that this is not the latest version available.

 

Have you tried uninstalling and reinstalling RealVision? Use the uninstaller in Data/RealVision_ENB_files before deleting anything.

 

Have you checked the settings in the Nvidia control panel? Make sure they match those on the RealVision description page (use the images, the written description is a little ambiguous).

Have double checked Nvidia settings as stated by RealVision

 

Am using 264 of ENB.

 

Reset the enblocal to using only 1GB of VRAM and still experiencing same issues in Riften, Largrashbur and Ivarstead; viewing the area from a specific angle causes my FPS to drop like a rock, even though never happened before.

 

Edit: now experiencing inside thieves guild...

 

Last thing I haven't tried is re-installing Realvision.  Hope this isn't mod related, I don't want to lose my save...

[nameless701]

Remove one of the videocards. 1GB VRAM is not enough for SLI.

The version required for RealVision is v0.262.

Follow this guide http://www.nexusmods.com/skyrim/mods/50214/?especially these parts of the guide are intresting for you:

-shensons memory patch

-skse/memory blocks log

 

Also you should really use the performance version of realvision enb with only 2gb of vram 2gb vram is the minimum requirement for real vision full and you only have 2gb on sli base togheter with other graphical mods not releated to realvision you are overloading your allready overloaded card(s) even more.

 

 

Had recently increased my uGridstoLoad, but I don't think that's the issue.

Of course this is an issue why do you think the ugrids are there? they are there to don't stress your system with a huge amount of details the more Ugrids you load the more vram and the more stress on your hardware. Possible you can run it anyway stable with the guide I linked.

 

Edit: upload your loadorder (active plugin list) please

 flashing between dark, light, and superbright. <-means not enough VRAM, dont use HD textures
