Increased performance of water displacement (parallax occlusion mapping).



Stuttering is not happen because of ENBSeries, it's drivers+game. Mouse movement by one axis is frame rate dependent (f*ng bugthesda) and i can't fix that. SLI is unsupported absolutely by my mod and i won't rely on it's performance difference between versions, for me nothing changed by fps when sun rays disabled and didn't anything which may affect performance seriously, for single card of course.
To optimize or not - this is not the topic of discussion, mod is always optimized (except first releases of some new effects) if compare to other games, if they have similar effects. More than that, optimization is one of my powerful sides as developer. Amount of features is too high by standarts of any games and this implanted to already awful slow game.

Witcher 2 game is far more superior by all means.

I repeat, version 0.236 not differ from 0.241 by anything performance consuming, except volumetric rays. Ask other users without SLI and they proove my words.

Witcher 2 game is far more superior by all means.

Trust me, the issue is not for lack of trying more optimal settings. I have all the performance tweaks I can stand without visibly reducing quality. I eliminated all LOD mods a long time ago (for stability reasons, as it happened to be.) I've compressed all my textures, eliminated texture packs I can live without. I've disabled ENB DOF (I did that a while ago, actually, kind of interferes with gameplay, and gains me about 4-5fps, although guess I could reduce the DOF quality and maybe gain 1-2fps and still be able to use it...not that that would solve my 20fps problem). I used to play with SSAO/SSIL at a much higher level, and was still able to attain 30fps+. I've reduced SSAO to 60% of my scree now, well below the 80% it used to be, in order to maintain the performance I am getting now, and I am still at 20fps most of the time. I've been on a long-term march towards lower quality in order to maintain the playability of the game with each new version of ENB. I know that there is a cost to the visuals...but I think the per-visual cost could be reduced to maybe 1/4fps each, rather than 1-2fps each.

I applaud all the new graphics features, but personally, I don't think they can remain unoptimized forever. I'm ok if Boris doesn't bother optimizing until he is done adding all the graphics features he wants to, but I don't think optimization should be foregone entirely. It should be done at some point, because each and every new graphics feature is sucking frame rate down by 1-2 fps. Add another several new graphics features, and I'll be stuck playing the game at 50% SSAO and 15-20fps...and that really bums me out, especially if I could be back up to around 30fps if some optimization was done.

I totally understand that optimization is the ugly, boring, gritty part of coding. I'd hate it too. In the long run, though, it's what will polish off ENB in the end, and make it not only a means to make Skyrim utterly beautiful, but also keep it playable for a lot of users as well. Not everyone wants ENB just for the sake of screen archery, in which case 15fps isn't an issue to start with. All I am saying is, I'm putting my vote in for optimization to occur at some point. Doesn't necessarily have to be right now, but it would be great if it was done before Boris calls it quits on Skyrim ENB entirely.

You must really be doing something off. check out my system specs in my sig. Much less than your reported specs. using a fully featured configurtion for enb, tons of textures replaced and still 35-45 fps out doors and 50-60+(with vsync disabled) indoors. Are you using lots of scripted mods? They can really slow down a system.

No not crossfire just single card, the twin refers to the GPU cooler not two of them. yes more RAM and I am not as familar with Intel chips but I thought almost all of the I7 outperformed the Phenom II class chips. Also my OC is only 300 MHZ on my CPU.

As boris said, SLI and Crossfire don't play well with skyrim in general not to mention with ENB

Listen, 30 fps vs 20 fps is difference between 33 and 50 ms, so you blame me for 17 ms loss in performance after updating from 0.236 to 0.240? It's how much cost ssao for me on old gf9600gt card, not funny. Disable SLI and compare two versions. Disable clouds shadows and sun rays and compare two versions.
