Negative acceleration ?
 

Got the game, 1.1 patch + 1.6 unofficial, with sound fix & HUD optimization.
Always had negative acceleration (aka input lag, mouse smoothing, etc)

Anyone else encountered that ? are there any fixes ?

I had this problem with precursors, not with white gold really though. I tried all sorts of things with precursors (which uses basically the same engine) but in the end only a CPU upgrade made any difference. An i5 did the trick for me, what hardware are you using?

Try turning down the settings and see if that makes any difference.

I have a core 2 quad q9550, 8gb ram, with 560TI 1GB.
I hit around 30-40 FPS on first island, I tried changing settings to both low & high (including config tweaks) and did not see even a slight difference in negative acceleration.

But thanks for reply mate, is good to know this problem is not universal !
I actually suspect is my poor generic mouse with this particular game (no problems with other games), long due for an upgrade so will see if it helps ey.

Ok here's an update, I have tried with 2 more mice.

CM Storm Spawn - exactly same negative acceleration, no acceleration in other games.

Logitech M90 - got positive acceleration in game, however I get positive acceleration in any other game as well.
Maybe it's the odd 1000DPI, but honestly I think it's just a crappy sensor.

Ok I have spend many hours now on this issue, even went out and bought some mice just to try - I pretty much have no idea why this is happening …
I'm leaning towards badmofo's explanation it's poor engine implementation (maybe deep shadows didn't even separate input to different threads)
I do notice it's not acceleration per se but more like input lag, if I move the mouse really really fast it barely moves at all ! (I guess that's what really annoys me)

I have finished boiling point several times and really enjoyed it, but there's simply no possible solution to this problem, maybe when I upgrade my pc I'll try it again, who knows.
