I have some strange and annoying LOD issues in The WItcher 2.
For example, in Act I when I'm walking in the forest, some small trees and grass keep appearing from the air rather close to me if I walk forward.
Another example, if I come closer to some wooden fence, the textures change abruptly to higher resolution ones at rather close distance, and it's really noticable, and breaks immersion.
And things like this happen all over the place, which is really frustrating for me because I've bought Collector's edition of TW2 and a decent graphics card (GTX 580) specifically to play it, so I expected really good graphical experience.

What I want to ask is: Is there any way to completely disable LOD system? So that the highest resolution textures are used no matter what distance to the player? I think that a GTX 580 with 1536Mb of memory should be able to handle everything in max detail at all distances.

Edit:
I'm on Windows 7 Ultimate x64 with 4GB RAM, Intel Core i5-760, Asus NVidia GTX 580 1536MB.

All settings in advanced tab of the configurator are maxed except for ubersampling.

I'm guessing you've turned off texture downsampling and have texture memory set to very high? Not sure if that would help with the LOD issues to be honest but still, weird you're experiencing that - I've got the LOD distance set to Near and only occasionally notice things popping into the background. Not enough to be distracting or anywhere near as bad as anything you've mentioned.

have you changed the LOD setting in the advanced options? In the launcher before you start the game

Yes, I've maxed all settings except ubersampling. I've even tried to manually set TextureMemoryBudget in User.ini to higher values like 1100, but no luck. Still things popping from empty air rather nearly and textures noticeably changing when coming closer to some objects.

Very strange.
are you using the latest Witcher 2 nvidia hotfix drivers?
Have you tried putting everything to default in the nvidia control panel?

In User.ini, the LOD distance is MeshDistanceScale. The value for far is 1.2 - no idea if it'll work but try setting it higher.

The higher the value for that setting, the lower the LOD quality. I believe .5 is or close to the 'minimal' settting. So Jerff, try setting MeshDistanceScale in user.ini to maybe 1.2 for 'far' or maybe even higher? 2?

Are you sure? I just tested it now and the values are:

Minimal: 0.5
Very near 0.75
Near 0.9
Normal 1.0
Far 1.2

Yup you're right! I got it backwards. Fixed my above post.

it's probably working as intended and he just is obsessed with popups.

Texture Downscaling is an opposite setting. For increased performance you want it on high. For increased quality you want it off.

Just thought i would post an update to this.

In the user.ini file you can change the MeshDistanceScale to higher amounts to make the LOD mesh change to be much further away, for example the max far setting as posted is 1.2, if you change this to double/triple etc the amount the LOD mesh change draws further away without issue.

I have mine set to 4x the amount (4.8), below are a few screens took showing the difference (look at the big pillar).

Default far setting.

4.8 custom setting.

As you can see there is quite a difference, if you set it to at least 6x the distance (7.2) the LOD change is really hard to spot as it's so far away.
---
Now, when you manually change this setting in the user.ini DO NOT re-open the launcher options menu as this will reset the setting back to the default low setting of 0.5, this also applies to the texture memory setting you can increase the amount (i have mine at 1000) to use more memory for textures but if you open the launcher options it resets to the lowest setting again.

testing now.

Thanks !
