I have encountered a weird performance bug on the PC demo of Mass Effect 3, that I wanted to bring to light today. I'd like to think that this demo is from a months-old build and that the issue has already been ironed out, but I feel it warrants mentioning in case others have also been having the problem.

The demo booted up fine, I got through the character creation steps no problem, and performance in-game is looking great, Fraps reporting a silky smooth 60+ frames per second. The problem comes when I finally get control of Shepard for the first time on the rooftops. Whenever I keep my view still or only move it around very slowly, the framerate continues to flow at a very stable 60 frames, but the moment I move my mouse around more quickly, the performance takes a massive dip to below 5 frames, and continues to do so while I am moving the mouse around rapidly. This renders the game horrendously unplayable for me.

Initially I believed that the issue was with the motion blur effect in the game, as I have sometimes experienced framerate dips due to motion blur shaders. I manually disabled the effect using the config.ini and tried it again. Same issue. I decided to leave it a while, update all my drivers and come back to it at a later time.

It was on my recent attempt to play the demo that I noticed that the framerate wasn't just dipping while I was running around shooting. I don't normally move the mouse around much when dialogue scenes are playing out, but in a spur of the moment fumble with the mouse, I noticed the framerate took yet another massive dip, despite no camera motion of any kind happening because of my movements. I experimented further, going out to the main menu where by all rights moving a mouse should have no impact on the performance. Upon just moving the mouse up and down at the title screen, Fraps recorded a familiar dip in performance, the game barely managing 10 frames per second. As soon as I stopped moving it, 100+ frames.

This is one of the most bizarre performance bugs I have ever encountered in a game, and it's quite surprising considering both Mass Effect 1 and 2 ran flawlessly. I hope this issue has already been addressed come launch of the full game, because I'd hate for such a stupid bug to ruin any attempts at continuing Shepard's journey.

For your reference these are the specs I'm currently running the demo with:
Intel Q6600 CPU
GeForce GTX260 896MB
4GB DDR800
Sound Blaster Audigy 2 ZS
Logitech G9 Mouse

If anybody has any ideas on the cause of this problem, and how to fix it, please let me know!

It does *sound* like a weird graphics driver issue. I assume it's nothing to do with the mouse smoothing option going wacky in the game options?

[ArmagonNo1]

I tried toggling each of the mouse settings but there was no change.

I had the same problem and fixed it by disabling Origin In Game. You can find this Option under Origin -> Settings -> In Game

Yes, others have the problem -> http://social.biowar...4/index/9271263

Disabling origin should fix it and is the first solution in the thread I linked. That however didn't solve the problem for some.

Other thing you can try is to reduce the mouse polling rate which I did so I could use the overlay. Posted the problem in origin forums also -> http://forum.ea.com/...st/8187442.page

I'll give that a go!

That seems to have worked, perfectly smooth framerates throughout now. Thanks guys!
Bring on the full release!
