This issue tracker is NOT for help or support. Please use one of the following channels for help and support:

Before you report a bug make sure you have tried the latest nightly version of Lakka at https://nightly.builds.lakka.tv/latest/. Your bug might be already fixed.

If you are sure that it's a bug in Lakka, please answer the following questions:

cpu gov: max performance (also tried per core max performence) monitored /proc/cpuinfo whilist testing and cpu clockspeed stays at max(3800 MHz or so) so gov looks like it's working reduce resolution back down to 640x480 brings fps back up to a fairly consistant 60 my previous settings on latency for 8/16 bit cores mostly had a delay frame of 8-9mseconds after installing the latest nightly these started showing some more nuance drops (solid 60.02 to 58 spikes) so had to dial that back to 3-4ms I had to roll back to this build Lakka-Generic.x86_64-nightly-20210615-2a94fae.img.gz to restore prior perfomence (slightly later build might be ok but this is the one which felt right)

given that cpu is not throttle afaik. and it is most noticable on shader, higher internal resolutions this feels like a GPU perfomence regression of some sort.

Will it possible to get some log with createlog ?

Thank you.

is this in refernce to the Alpha Sorting option? this has always been set to Per-Pixel (accurate, but slowest) . did the this setting previous actually did nothing prior to the above commit? flipping it down to to Per-Triangle (normal) does indeed improve the framerate (but still seems to fall short a couple of frames overall). plus other cores seem to be slower too? notably ppsspp Tekken6 (bufferchain:2, 1020x1088 render target, 4x aniso) was 58-60 (with drops) is now 50 -57.

gouchi commented 3 years ago

@Ntemis nice catch ! I forgot we enabled it.

@auxfam Yes I think so, I remember correctly. If needed the compatibility list for OIT.

For ppsspp maybe it is only for some games but it is for RPi4 not x86_64 ?

ghost commented 3 years ago

it's unclear overall. I can only report the titles I replay frequently and they all have small regressions that you may not normally notice were it not for the fact that I tuned most of my core configs to sweet spots, unfortunately we have no reports from other users to corroborate this or otherwise. in general this just feels like an increase in performence requirements which for a project of this size can be expected over time.

I am ok with that being the case (in which case close this issue) but last thing I can say is that it's not just the x86 platform. I fired up my RG350p (ARM64) last week on the PSCx-ReArmed core and tried Tekken 3 (PS1) [ max 3 swap buffer, power profile:max, threaded video: defaults on everything else ] ~ 58-60 , [Thread video:off] 53 for ReArmed this feel far too low / unstable but again haven't had the time to go back and test older nightlies yet.

gouchi commented 3 years ago

If it is on other platform it could the update of the core or graphic stack.

Please reopen this issue or open a new one if the performance is getting worse.

Thank you for your tests and report.
