More on epilepsy in Cliffs of Dover

[BobTuck]

At this rate we will all be buying the Russian version of the game, with english language turned on.

At least CloD will then be as intended, muzzle flash, propellers, high FPS, everything...

Yes, lets vote with our money!

The information there is not accurate, especially the placing of the blame on Ubisoft.

I feel that I need to describe this in more detail.

Our game did cause wide-scale epilepsy failures when tested. Propellers, muzzle flashes, smoke puffs, explosions, falling bombs, flying or taxiing between buildings, sun shining through canopy framework, etc, they were all causing potentially seizure-inducing flashes.

We worked hard to address all these issues individually, but since a flight sim is all about fast-moving large objects, there were just too many instances of things causing high-contrast flashes.

So, as we were running out of time, WE decided to implement this epilepsy filter as a stop-gap measure.

The filter sits on top of the game's graphics wrapper. It saves a previous frame, and then compares it pixel-by-pixel to the new frame. When two pixels are found with a high degree of contrast between them, the new pixel is toned down to make the change less drastic.

This causes a visual effect somewhere between bloom and motion-blur that removes virtually all instances of high-contrast flashes.

However this pixel-by-pixel frame analysis and modification takes up additional resources, it in fact delays the showing of each new frame until each pixel of it checked, and therefore the filter is causing deteriorated performance that is especially notable on lower-end machines.

We are continuing to work to optimize the game and to increase its framerate. Ubisoft has been very patient and understanding with us throughout the entire process, and we are continuing to work with them very closely to find the best solution to epilepsy issues.

In summary, I want to stress that it is OUR code and OUR game engine that is causing performance issues. And it US who has to make it better, and that's exactly what we pledge to do.

Thanks for post.
I cancel preorder right now.

Any idea when the problem will be solved?

How Ironic !
Here in the US , we consider ourselves the world leader in freedom , yet because
of a few thousand greedy trial lawyers and the corrupt liberal polititians who support them , we are forced to tolerate this kind of crap while many of the other
"not so free" countries get to enjoy a video game in it's unfiltered version.

Sheesh......when will we learn

Tolerate?
There's nothing to tolerate mate, or you happen to have the power to change Ubi's mind, which from rumours seems to consist of solid rock. It's a take it or leave it scenario basically. The only big hope is Luthier and his crew right now, working on a way to solve it.

I don't understand how you could have a risk of seizure in daylight , night battles I could see but muzzle flash in broad daylight?

Very strange list - falling bombs? Taxying between buildings? How come these things in IL2 didn't cause any problems? How come these things things don't cause problems in other games?

Did all the game developers employed to create CloDo have epileptic seizures during the development process? What about the public allowed on the game at Igromir?

All in all rather peculiar.

RedToo.

Why are you assuming that they didn't cause seizures? The difference will be that the laws have changed, and now being aware of the problem 1C has a duty of care to take all resonable steps to minimize the effects. Otherwise they would be liable.

You will probably find the laws are not retrospective.

Depending on your view point, seeing a string of bombs falling in front of a bright background (sun, cloud what have you) would produce a series of flashes.

Elpilepsy is one of those things that can remain dormant is a person for their whole life, until the right set of events triggers an episode. The last thing I would want to interrupt my gaming session would be a over night trip to the children hospital if that trait suddenly decided to express itself in one of my children.

1C is just showing us how much they care for their customers.

cheers!
