Septerra Core: Windows 10 64 bit. Mouse stutter tied to polling rate? #30

Closed Crim001 closed 2 years ago

Crim001 commented 3 years ago

This SR port of Septerra Core is great! I've noticed, however that when using my gaming mouse that the mouse stutters constantly. I have realized that it is tied to the mouse polling rate. If I use my gaming mouse default of 1000 Hz it is very jittery. Buttery smooth though at 125 Hz.

I wrote about this experience a bit back on the GOG forums, but have decided to bring it to your attention here in case it may help others who are also having problems with mouse stuttering.

My mouse only has the standard 125 Hz polling rate, so I can't test this.

Can confirm this happens with my 500 Hz mouse as well. Unfortunately the manufacturer doesn't provide any software means to adjust the polling rate, so I can't confirm the fix.

Can someone test the attached executable whether it fixes the issue ?

SepterraCore-Windows-x86-test.zip

DukeSkinny commented 2 years ago

Seems to improve things somewhat on my end, but the issue remains.

M-HT commented 2 years ago

What about this one ?

SepterraCore-Windows-x86-test2.zip

DukeSkinny commented 2 years ago

Brilliant! Completely fixed the issue for me.

Crim001 commented 2 years ago

I can confirm that the SepterraCore-Windows-x86-test2.zip seems to completely fix the issue. I no longer need to reduce my mouse polling rate to have smooth mouse movement. Fantastic, thanks!

M-HT commented 2 years ago

Can you please also test this one ?

SepterraCore-Windows-x86-test3.zip

DukeSkinny commented 2 years ago

Works like a charm.

Crim001 commented 2 years ago

Confirmed SepterraCore-Windows-x86-test3.zip also works

Zombeaver commented 2 years ago

This fixes the issue for me at 500hz or below but it persists at 1000hz. I tried all 3 versions.

M-HT commented 2 years ago

Does test4 also fix the issue ?

SepterraCore-Windows-x86-test4.zip

@Zombeaver Can you try test5 and test6 if either or both of them fix the issue at 1000Hz ?

SepterraCore-Windows-x86-test5.zip SepterraCore-Windows-x86-test6.zip

DukeSkinny commented 2 years ago

Sadly, no dice with SepterraCore-Windows-x86-test4.zip. The last 2 still perform well.

Zombeaver commented 2 years ago

test5 and test6 both fix it for me at 1000hz!

Crim001 commented 2 years ago

test5 and test6 also fix the mouse issue for me. Interestingly though, if I have vsync disabled test5 and test6 will make the camera moving that occurs after battle before you get experience/results stutter and take an extended time to happen (test 5 is worse for this, I originally thought the game had frozen it was going so slow). test3 also does it, but is almost unnoticeable. Enabling vsync makes it move smoothly after battle like usual.

M-HT commented 2 years ago

I released a new version of Septerra Core. I added a new configuration option: CPU_SleepMode. The default value is standard. If you have a problem with mouse stuttering (because of higher mouse polling rate) then set the value to reduced. If that doesn't fix the problem, then set the value to nosleep.

@M-HT I do not know who you are, or where you live, but I will find you and I will marry you. THANK YOU!
