MOUSE-CURSOR FPS DROP
It has been for some time known that in FSX, the mouse cursor can cause certain FPS drop. It has always existed in FSX, however became known with the appearance of high quality cockpits that were hard on FPS. For example PMDG 737 NGX. If you are locking the FPS like I suggest in this blog, then your FPS are locked 30fps. Now, it will still happen at detailed airport hubs that your FPS drop below 30fps in the NGX VC. Say your FPS drop to 25. And the issue of the mouse-cursor lag or fps loss is simple: is there visible mouse-cursor over the FSX screen, the FPS will be lower than they are when the mouse is hidden. The mouse-cursor hides automatically after some 5 seconds if you do not move it. However, one might wish to hide it, not waiting these 5 seconds.
Beware, this is not really a tweak, it is only a way to help yourself gain couple of FPS during worst of times like taxiing on a big airport or on approach where FPS suffer due to high quality scenery.
Also note, that this “tweak” does not help if you are GPU limited. For example low speed GPUs, or extremely high levels of Antialiasing, which would put your GPU usage to 100% and limit the FPS on the GPU.
So, how to:
In windowed mode, it is pretty obvious, just move the mouse cursor off the FSX, and you will most likely notice FPS go slightly up (usually about 20%) – as long as your FPS are BELOW what you have locked, otherwise they can’t go up, obviously!!
Full screen is a bit more tricky, so I use two tricks – in NGX, there is a possibility to move to the left upper edge of screen, that is basically the same, or I personally use EZCA – I have a mouse button assignment for cockpit pan of EZCA, which then conveniently hides the mouse cursor and switches the mouse to react as a pan-around. Also if switch to another screen, like I do via InputDirector does the trick. There are many tricks, the main thing is, cursor is not visible over the main FSX screen.
