Brief Description from first post:

Abstract:
TESVAL is an in-memory code patch for TESV, aiming to fix a few of the worst CPU hogs.

Supported game versions: 1.3.10.0 only.

Description:

This patch will improve your frame rate by up to 40% in all CPU-dependent situations, i.e. especially in cities.
It works mostly by rewriting some x87 FPU code and inlining a whole ton of useless getter functions along the critical paths because the developers at Bethesda, for some reason, compiled the game without using any of the optimization flags for release builds.

There has been some confusion about the original dll file and the current one for Script dragon.
Script Dragon's dinput8.dll is 592kb
The non working TESV Accelerator dinput.dll is 74kb

From the readme prepared by Ianpatt


TESV Acceleration Layer (1.3.10.0) Proof of Concept by Arisu
(small port to an SKSE plugin for compatibility by ianpatt)

Installation instructions:
1. Install SKSE from http://skse.silverlock.org, instructions are in its readme.
2. Drop TESVAL.dll from the archive above in to /Data/SKSE/Plugins. Create the SKSE and Plugins folders if they don't exist.
3. Run the game by launching skse_loader.exe.

Using the SKSE version of TESVAL has my fps at the entrance of Markarth improved from ~48-51 to 61-63. I can now sprint through all of Markarth and Whiterun at 60 fps solid (vsync on), even overlooking Whiterun from Dragonsreach entrance.

Thank you to everyone involved in creating this fix, and even more for releasing the source to the community.

SO far so good, I had one "Exclamation DING!" crash when I was doing a bunch of alchemy on the alchemy screen.
(couldn't see the pop-up, because the screen froze and I had to End Process from Monitor 2 that I keep the Task Manager open in when playing Bethesda games

But my framerate has gone up a noticeable percentage, I'll keep trying it, and see if my crash during alchemy was just a fluke

I happened across a post talking about this in the tech forum. Gave it a try, IT WORKS, YAY!!! There is a definite improvement of fps in the difficult areas. For me, steps of Whiterun now 30 fps, previous 24 (~25% improvement). Markarth worst spot ~20 fps up from 15 (~33% improvement). Thank you so much for this and Bethesda take notice. Modders polish your games when you should be. For shame.

Are you going to put this on Nexus? Are you hosting on any other site?

[Fanny Rouyé]

I have noticed a decrease in random ctd's and an increase in performance too.

[A Boy called Marilyn]

I was highly skeptical that areas such as Markarth, Whiterun, and even some forts out in the woods (holy hell, fighting a cadre of necromancers is annoying with FPS in the low 20s and the associated mouse lag!) would ever be "fixed!" Thank you to those responsible for this amazing mod/patch!

Running on a PII 955 @ 3.6 with an HD 4850, and I don't feel like my rig is choking when I run through the cities. It's glorious.

[ashleigh bryden]

Quickly tested save near riverwood. Vanillla is 19 fps and with the plugin its improved to 25! Yay! Awesome stuff!

Though I can't speak for ianpatt, as far as it concerns me, anyone may upload/host it anywhere and generally do anything with it.

I have asked Arisu for permission to upload this to Skyrim Nexus. Once I have his permission, I will upload it there.

Looks like the author posted while I was posting. Expect it there shortly.

Arrrr Asking for 3rd time - r u going to continue accelerator developing ?

[Chelsea Head]

What is this and what does it do? The description doesn't say.

[Jessica Lloyd]

This plugin replaces some "bottleneck" code in the executable so it runs a bit faster

[Angelina Mayo]

I found the original description of what this does and added it to the OP.

[Melanie Steinberg]

You know what else this did? This let me run 1.3.1 without constantly crashing out. Not kidding I couldn't run it on 1.3 (1.3.1 is new). I was running a backup of 1.1.

I can't explain why, it just does.

I haven't tested for long, but it does seem to have reduced stuttering. No slowdown in Markarth (though I don't have much to compare). High detail, mostly vanilla otherwise.

AMD Quad 2.5, 4gb, 32 bit, 4890 1Gb

So, you know, good news!

My apologies, I was sure I already sent you a message, but it seems it has been lost.
To answer your question: I don't even know that myself, yet. It highly depends on what Bethesda will do with their next patch, when exactly it will be released, and so on.

While it's also possible to continue adding more patch locations to the current version, the fact that all the simple stuff has already been eliminated means that a point has been reached where it becomes increasingly time-intensive to reverse-engineer code with smaller potential performance gains. I must realistically say that I most likely can't add much during the Christmas and New Year holidays.

Also, considering that the LAA-patch just arrived shortly ago and the holidays begin now, I kinda expect the game to stay at this version for the next few weeks at least. The future will tell what the best options for proceeding from here will be.

I had to figure out how to get the actual file to upload. It is there now. Sorry it took so long.

I've heard http://www.gamesas.com/topic/1322003-holiday-update/of 1.4 patch coming in January around the same time as the CK.

You should really remove that info about d8input.dll. That is no longer really valid. Everyone should be using the SKSE version at this point. It will just confuse people and cuase problems.

[KIng James]

Yes, consider anything I added under that license as well.

Arisu: out of curiosity, which sampling profiler do you prefer for x86?

[KIng James]

@Arisu
Using amd profiler I was able to find few dozens of other critical bottlenecks of the same type as u fixed =)

Thanks and done.

Why the HELL does this have 0 endorsemants on nexus? It's a work of genius.
Perhaps I just care more than other people about a framerate boost and they don't notice/care about the extra frames.

I just went from an already high end cpu (corei7 860 @ 3.9ghz, unstable due to age and cheap/partly dysfunctional motherboard) to a slightly newer chip and motherboard (corei5 2500k @ 5.2ghz, stable) And the performance boost in skyrim was less than other cpu intensive games. However it did remove the 25-30fps lows in certain areas and replace them
with 45-50fps lows (The upgrade cost me $360AU) . This takes that from 45-50fps lows to 55-60fps lows. With the exception being exact standing points in cities, like precisely the top of the stairs
at the top of the stairs looking down at the tree @ whiterun, which is now 45fps. (all this is at 2560x1440).

So it's like that little bit of upgrade I needed on top of the physical upgrade.. I still can't run 8k (distance) shadows mind you without getting more frequent lows. However this mod allows almost a universal 60fps.

Now I just need the skyrim stutter remover to take away that horrible vsync interior stutter due to the 64htz bug (not sure if it's ATI specific, people say that gtx 580's don't
get interior stutter, full stop. So perhaps it is ati. Typical) and I'll have a great running game.

Sigh. I still wish I went SLI 580's instead of 6990. Ati really got the raw end of the stick when it comes to skyrim performance.


Also, all of this 60fps talk is due to me needing vsync. Most open-non-city areas give 80-90fps with vsync disabled, however as it reaches this number the perceptible frames reduce due to microstutter (so it actually seems like 22fps instead of 90fps). So you need vsync to create a smooth looking game. The drawback, and my mention of the 64htz bug, is that vsync brings with it it's own kind of stutter. Where it get's uber choppy in certain interior corners and... pretty much caves in general. Unfortunately this mod does not fix that at all.

This mod deserves 2000+ endorsemants.

[Damien Mulvenna]

I'm a little reluctant to install this.

For one, because I already get fairly decent performance (more than playable) and two, I'm not sure if the alterations made to the code to improve the performance won't have some sort of lasting side effect that the modder hasn't foreseen.

I don't doubt that Bethesda might have not used some optimization protocols when they compiled the game's code... but at the same time, there might have been reasons for them doing so. Something may not have worked correctly when ran through a compiler's optimizations. Something deeper than what we might notice at first.

[Brad Johnson]

It hasn't been up on Nexus long enough to get any endorsemants. I am truly thankful to both Arisu and Ianpatt for getting this plugin made and available through SKSE, It makes a huge difference on my computer.
