| Summary | 0005363: Poor performance that randomly occurs throughout an entire game | ||||
| Description | Sometimes I notice that ZK is running with very low FPS (<15), even in the early stages of a 1v1 when there are few units. This low FPS persists for the entire game. In other games the performance is fine. I have heard similar reports from other people. I have run the ZK benchmarker and found a similar result, around half the games have a framerate around 10 while the others have a framerate around 30. https://docs.google.com/spreadsheets/d/1zF_iFzwMiWR0J2lLfgiyH9z5-Vff6wq8vjZgqNKa2Xs/edit?usp=sharing | ||||

I have not finished bisecting with the benchmarker. I thought the problem started around 103.0.1-90 until I collected more runs. I will run more runs around 100.0 to 103.0. |

try to get a screenshot of /debug during the poor performance |
|

Here is a set of screenshots with debug view. http://imgur.com/a/y2mAM The screenshots compare the framerates of icon view and rendering view. At first I thought that the performance issue was to do with rendering so I modified my benchmarks to have a zoomed in view of the game. Then I forgot about this connection and forgot to include it. My current benchmark is a 6v6 East vs West AI game. Factories selection and placement is hardcoded in a gadget, all factories are Shield factories. The camera is fixed looking at the center of the map like this: http://i.imgur.com/9HXOzQ0.jpg The game is run at 20x speed until 7:55. "speedy_dt" measures how long it takes to get from the start of the game to 7:55. This time has been increasing with the past few engine versions which may also be a worry. "w_update_dt(avg)" is the average time between widget:Update calls between minutes 8 and 9. The other important bit of data is "units_start", this is the number of units at minute 8 and exists as a sanity check to make sure the run looks reasonably normal. |

Ok, it seems to be something with projectile drawing. Did you check if it replicates consistently when running a demo? |
|
|
Yes, I will attach a replay which reproduces the issue. I don't think projectiles are related because barely any projectiles are used in this replay. |
|
|
Check the screenshot. DrawProjectile takes a disproportionate chunk of time |
|
|
You may be right though, since graphics lag doesn't necessarily affect the part responsible |

The cold snap replay shows some very weird behaviour, shown in screenshots here: http://imgur.com/a/PHb1q By 22:19 I have low FPS with a normal camera view. I turned off luaui and luarules to remove the effect of lups and had a look around to see what was causing it. I found that FPS can change significantly based on the location of the camera. An example of this change is in the second and third images of the album. Both images were taken at 30:09 while the game was paused. The only difference between them is a small camera movement. To reproduce this just zoom out to a similar level and move the camera around while keeping track of your FPS. The dependence on camera position might mean that the benchmark variation is not due to a significant difference between the games. The variation might just be due to what is being viewed. |

|
can you attach the exact an infolog from viewing this replay? |
|
|
Here are some more screenshots http://imgur.com/a/CvkR9 from this game http://zero-k.info/Battles/Detail/432113 |
|
|
in several screenshots there are 10k queued updates. this bug report is a bit confusing: there are screenshots of game a demo of game b infolog.txt game c all this info from one game would be much more useful. |
|
|
The most updates I saw was 0001017:0002500 (remember these are 2 numbers), anyway, there seems to be enough info currently. I'll have to work on it before if/what I need more |

Ah sorry, I thought you've meant the latest imgur link |

The GeForce Windows 10 64-bit driver version 373.06 (latest driver) may have fixed this problem. I have had no problems so far and can report back if the fix was just a fluke. I had previously tested a few driver versions, however, this driver was released on the 6th of October. The bug may be caused by my GPU powering down after running Spring for a few minutes. The load on my GPU core could go as low as 15% while I had poor FPS, I will attach a screenshot to show what I mean. The new drivers seem to have fixed this problem. |

this time: nvidia sucks ;-) @Google_Frog: thanks for investigating this/the feedback! |
