I've reinstalled the game and nothing changed; the stuttering persist only on that character. With a weapon or another, with or without robot summons, high or low graphics, it is unplayable (but i've played an imperial knight mission without problems). I don't know what's the issue. 

Now that the seasons are all accessable, there is the possibility to end the season early? Maybe the problem is related to the season (altough it worked all fine until last week); if possible i don't want to delete the character.

Thanks for the help.

Yes, exactly.

I counted the points: i'm down of 4 beside the 105 marked. For the stuttering i'm dubious beacause the other characters, even psykers with heavy effects on display or a tech adept with 10 more robots than the one unplayable, play normally. Besides i have frame blending on with both brightness and contrast at 90, gamma at 50 and saturation at 1.0 (almost all settled in the middle of the bar); do you have suggestions on balancing? It is an unbalanced video setting? Thanks.

P.s.: i have since years a lot of numbers and effects turned off.

The character is elexii-3 and its the only seasonal and is still unplayable;  i've noted that the stuttering occurs only during combat if can help you with the problem. For the trick  you mention i play on playstation and i don't know how to do it. Do you know?

Sorry to continue to bother, but now i have another, more serious problem; the same character, seasonal, now is unplayable due to high stuttering during missions. I've tried other of my characters to see if was a general or playstation problem but they can be played normally. There's something you can do?
