Input Lag. Need a fix.

[Acno]

The graphics are fine and the frame rate is normal, but whenever i click with my mouse or hover over an item it takes half a second for the description to show up, and there is a delay when I try to move my character.

It's really frustrating, please help!

Does it make a difference if you change the game resolution, video options or switch to windowed or fake fullscreen mode?

Are you shutting down all non-essential programs (especially anti-virus) before starting the game? Maybe freeing up more resources would help.


Try disabling the deferred renderer for the game; that has helped some people with input lag, though it is more likely to cause a crash on startup than help. It is easy to check, though, and easy to changed back.

In the '..\Documents\Larian Studios\Original Sin\graphicSettings.lsx' file, search for the term 'RenderDeferred', and in the second row after that, change the one to a zero, and save the file.

<attribute id="MapKey" value="RenderDeferred" type="22" />
<attribute id="Type" value="0" type="5" />
<attribute id="Value" value="1" type="4" />

I'm also having what I'd call "input lag" while using skills or receiving damage from enemies. There is a split second pause on the initial skill use of almost every skill. So for example, if I haven't yet summoned a spider, the first time I click to cast, there will be a stutter on click and also a stutter at the moment I place the spider and he's summoned. This also happens with any buffing spell. After I've used the spell, and I use it again, no pause or lag.

I've also seen it happen with a simple "MISS" text. Enemy shoots an arrow at me, it misses but it will pause for a split second before the MISS text pop up.

I tried the fix above, only crashes the game. I've tried with disabled and enabled texture streaming, still get the pause. Tried with shadows disabled, no AA, low textures, all fullscreen options, adjusting windows memory usage preferences, nothing helps. Every fight is filled with this horrible pause/lag and after 25 hours I can't take it anymore.

I can't play another 25-50 hours like this. Any help would be appreciated.

I changed my DEP setting to be on for only essential windows programs (off for D:OS) and this solved all my stuttering problems, from texture loading to the input lag I described above.

MAKE SURE DEP (DATA EXECUTION PREVENTION) IS USING ITS DEFAULT SETTING
To do this, follow these steps:
1) Open Menu Start
2) Right click 'Computer' and click 'Properties'
3) Click 'Advanced system settings'
4) Open tab 'Advanced' and click 'Settings' in 'Performance' section
5) Open tab 'Data Execution Prevention'
6) Change DEP setting to the first option (Turn on DEP for essential Windows programs and services only)
7) Confirm with OK.

Do you also need to do the fix Raze mentioned? or will your method alone fix the input lag?

No-- I tried it but Raze's method prevented the game from starting at all.

I also have disabled "real time protection" in my antivirus (Microsoft Security Essentials) while the game is running, although I'm not sure that's necessary with DEP off. I'm sure DEP was the trick.
