I'm considering removing legacy deferred option. It was mainly there for folks with much older PCs a few years back. These PCs would no longer be compatible with modern builds in any case. I'm not sure this option serves any real purpose now other than to degrade lights and rendering quality. :)

Version 2.3 released, download link on first post. This comes with new awesome textures from VMblast, which really add a new life to this mod :)
If you prefer, you can enable the old look from settings, at least for now. As always, the source code is available here, if anybody want to contribute.

Very nice Lacus!!! Thank you!

I remember about the mist and flying bugs you talked about, is that still a thing which might eventually be implemented? It looked awesome as well.

I decided to choose quality over quantity and only kept a few butterflies and fireflies at random spots.
I figured that making mist effects look the way i intended would require too much time and would better be part of a weather/climate mod, which is not something i'm interested in right now.

It looks awesome! At this rate DFU will soon rival games like Skyrim in terms of graphics. :D

I did not try DFU in quite a while, but with the latest build (#139) I noticed some performance issues when this mod is active. It manifests as a minute lag (frame-rate drop) like every two-three seconds. It only happens when I am moving, when standing still and only rotating the camera, the frame-rate is stable 60fps.

I have tried to find out which setting is responsible, but even with grass distance set "1" it is still noticeable. Setting it to "0" obviously fixes the problem... :D No other settings made any difference.

My system specs: Win7 64bit, Intel i5 3470 @~4GHz, 16GB RAM, GTX 1060 3GB.

My ideas:
- VRAM usage is bordering 3GB with real grass enabled... without it I hover at ~1.5GB, so I was wondering why this mod is so demanding on VRAM.
- Maybe it is that the generation of "new" grass as the player moves causes this.

UPDATE on my performance issue:

Insufficient VRAM is not the culprit.
Explanation: Yesterday my VRAM usage was high even idling in windows, at around 1.2GB, I did not know whether it is normal or not. Running DFU with the grass mod it has gone to 3GB. However, today my idle VRAM usage was only ~240MB, so even with the mod fully enabled, I have reached max 2.3GB VRAM usage and the periodic lag (frame-rate drop) was there.

The lag is present even with the mod toned down with all the settings disabled (plants, flowers, stones, insects) and the grass set to billboard. Distances and such were left at default. VRAM usage ~1GB. (Practicaly the same as with the mod disabled BTW.)
- Switching to mesh grass increases usage to 1.2GB.
- Adding water plants ~1.2GB.
- Adding flowers ~1.9GB.
- Adding stones ~2.2GB.
- Adding insects ~2.3GB.

Thanky you for you detailed report ifkopifko. :)

A known problematic moment is terrain creation and initialization. When you walk in the open world and a new terrain needs to be created, a small frame drop can be experienced, even with all the recycling and optimizations. If you install a mod that works during terrain setup, like this one, the issue can only be aggravated. This should only occur when a new terrain is generated though, if you have a constant lag it's probably something else. Does anybody else have this issue or worse performance that previous versions in general? Realistic option disabled should give the very same result as previous version.

I will check memory usage and see if there is something off.
