Windows 7 (RTM, MSDN)
DisplayFusion 3.1.4
I used to run Ultramon when I had XP, but installed DF recently when I moved to Windows 7.
As soon as I had installed DF, games (listed below) became very choppy whereas beforehand they were very smooth. Interestingly there was not much of a difference in FPS. The choppiness greatly affected mouse input making the mouse 'skip' inconsistently. That is, the rate of movement jumps drastically at random moments, and is generally inconsistent.
I tried checking my mouse, but got the same skipping with 3 mice (with corresp drivers installed):
- Razer Deathadder
- Logitech mx518
- Razer Lachesis
... using a Razer Destructor mousepad. Since all mouse skipped, I next did software isolation tests:
[list type=decimal]
standard bootup environment. DF running
standard bootup environment. no DF running
bare essentials with all background processes closed. DF running
bare essentials with all background processes closed. DF not running
many extra background processes. DF running
many extra background processes. DF not running
[/ul]
The corresponding results of this were:
[list type=decimal]
skipping
smooth
skipping
smooth
skipping
smooth
[/ul]
This behaviour was consistent with the following fullscreen games:
- Team Fortress 2 (steam)
- Counter Strike: Source (steam)
- Call of Duty 4 (non-steam)
I have installed the latest videocard drivers (nvidia 8800GTS 512mb), and directx drivers (DirectX 11), and the Windows is genuine and up to date.
I am running two monitors at 60Hz:
[list type=decimal]
1680x1050
1280x1024
[/ul]
I can only conclude that DisplayFusion is the culprit here. Please find a fix for this behaviour because I dont want to go back to Ultramon since it has poor Windows 7 support
