Larian Studios Forums Divinity - Original Sin Divinity - Original Sin - Technical Issues Delay Lag

I've been playing the game with a friend of mine and for some reason or another he has encountered a performance issue that we can't quite figure out.

Both of us have a delay when hovering over options on the Main Menu screen, but it only amounts to maybe half a second long. But now he has a delay similar to this when trying to select skills and when trying to activate them, AKA when he clicks an enemy with the selected spell or ability to set it off. He says it takes a good few seconds for movement/skills to register now, and it's -extremely- irritating.

He has tried fiddling with the game quite a bit to get rid of it, but to no avail. Even re-installing has had no affect.

As of right now, he has no interest in continuing to play this game because of this, and we would both very much like to get this fixed. Suggestions/Ideas?

This may help for mouse input lag:
Edit the graphicSettings.lsx file (in the '..\Documents\Larian Studios\Divinity Original Sin' folder) in Wordpad, or other text editor, and search for 'RenderDeferred', then change the one to a zero.

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

Yikes.. Non-deferred renderer is heavily broken. I'd highly suggest never to touch it

Well, I attempted to adjust it as said, but all it succeeded in doing was making my game unable to start. It just gets to the black screen that normally comes up before the game fully loads (normally lasts all of a second or less), but instead of continuing it just crashes to desktop.

My friend has yet to try it himself, but either I'm doing something wrong or this can't work at all.

Thank you for the idea though, it's better than silence!

Do you have any "enhancers" that constantly "spam" system with windows messages? This could be just anything - antivirus, additional desktop candy, etc?

The idea is that DOS extracts windows messages in a loop one by one and processes them. On Windows it extracts only one message per frame. This means that if application queue is filled with some 'trash' messages you will definitely have severe input lag.

If you're a developer - I'd suggest checking this stuff using WinSpy++ stuff, in other case just try to make your system as free from any add-ons as possible. Close browsers, terminate downloaders.. Then try and see whether it makes any difference.

This is not true. I am a gamedev myself and you would definitely not only extract one message per frame. If this is the case that code needs to be changed. But true, if the message pump is flooded with messages it might slow things down a bit.

It also depends on the input system used. If D:OS uses DirectInput it does not use Windows messages at all.

No, I avoid clutter as a rule of thumb. Only background program I have is Skype and the built in firewall.

Okay, an update. While it still doesn't work for me to remove the extremely slight input lag on the Main Menu simply because I can't reach the Main Menu, it has apparently worked perfectly for my friend who had the serious problem. I have absolutely no idea why it crashes for me and not him... but I'm not gonna complain.

Thank you for the help!

I am also having an issue with input lag. Running on a laptop with an i7 multi-core processor, with 8gb of ram (dedicated video card with 1gb of ram). I also tried the RenderDeferred setting that Raze mentioned, and it crashes to desktop just like Vladmorik mentions.

This is a game-breaking bug for me, and it comes out to be a waste of 40 dollars. Someone please look into this issue at Larian.

Please email supportdos@larian.com, with a description of the problem and the report.zip file generated by the D:OS support tool (for the PC version). The report will contain system and game information, as well as your saved games. To reduce the file size, you can delete all but one save from the zip (since the problem is consistent and probably not related to the save itself).
