Synthetic Sensor Testing
This section is an evolving endeavour to improve the objectivity of mouse reviews here at Play3r, it shouldn’t necessarily be used to compare mice apples to apples but it should help us get a better feel for the quality of sensor implementation. The programs being used here are homebrew, so these results should always be taken with a pinch of salt but I think it is essential to supplement the subjective content of my reviews with some (slightly) more scientific testing.
All my testing is done on an OcUK Mega Mat XXL
Enotus Mouse Test v 0.1.4
Enotus mouse test can give us a few bits of sensor information such as DPI and polling rate. The methodology used in this benchmark is to always run it at the maximum DPI the mouse supports and also at 1000Hz.
Enotus mouse test gave us all the results we would expect from an Avago 9800, with the main negative point being of course the inherent acceleration present. All else is well though so if you don’t play FPS games you shouldn’t have any issues.
Mouse Movement Recorder
This benchmark gives us a direct feed of sensor reading versus pointer movement and it also gives us an approximated polling rate. This benchmark is done on an open and run basis, but we run it at both 500 and 1000Hz to compare the two.
1000 Hz
A strong point of the 9800 is its very stable polling rate which we can see demonstrated here.
Paint jitter testing
This test is a bit less scientific, but drawing lines in paint gives a good visual representation of any jitter present. The methodology here is to perform the test at 1600 DPI, 3200 DPI, and finally the maximum DPI of the particular mouse which gives us means to keep results more consistent between optical and laser sensors. All tests are run at 1000Hz.
1600 DPI
3200 DPI
8200 DPI
The M65 also displayed no noticeable jitter, even at the sky high 8200DPI maximum so all is well here too; again for anything other than FPS games the M65 RGB will do the job really but that inherent acceleration from the sensor is a real downer as always with 9800 based mice.
