1.4.1.0 vs 1.5.2.0 performance comparison

[Geronimo]

Hello everyone!

Since 1.5 I have major framerate and frametime issues to the point where it's no no longer fun to play the game so I decided to to a clean install with the 1.5 full installer. (spoiler: That didn't help.)

And because of that I had to uninstall the game anyway so I decided to grab the 1.4.1.0 installer first to see how much the performance between those two versions differs.

All benchmarks were done for 2 minutes on an empty local server standing still and looking towards a specific spot. No LODs was unticked because 1.4.1.0 doesn't have that option and the framerate cap was removed with game.lockfps 0. All other settings were on max @1080p60hz.

I know that those benchmarks are not super scientific but they should be conclusive enough to give you guys a picture. Also keep in mind that the framerate and frametime graphs only display the last ~15 seconds. And lastly minimum framerate is higher than 0.1% low framerate for some reason so maybe ignore the former.

                     Average framerate  :  178.9 FPS

                     Maximum framerate  :  181.0 FPS
                     1% low framerate   :  112.8 FPS
                     0.1% low framerate :   70.6 FPS

As you can see Fallujah West saw a decline of 10% in average framerate and 1% low framerate dropped by 19%.
Average framerate on Wanda Shan is 41% lower and 1% low framerate is 38% lower.

The 0.1% low framerates are a bit misleading in my opinion. Those are so low for 1.4.1.0 because that version had a single framerate spike every ~30 seconds but that was hardly noticeable during gameplay. Nevertheless 1.5.2.0 doesn't have that problem.

Thanks for the benchmarks. I assume you used same audio settings for both? That would confirm that EAX has nothing to do with the drop. We still dont know where it is coming from as we did not really add anything new to the client (apart from new models etc, but those should not matter when not loaded). All new gameplay features are serverside. Then again that could impact performance when playing locally.

[Geronimo]

Yes, EAX was on for 1.4.1.0.

[Mats391]

And are you experiencing similar drop when playing online? You could test on NWG, thats always empty and on Fallujah

[Geronimo]

No servers were running Fallujah unfortunately so I used some other maps.

Guess I cant blame python then
Thanks for the tests

Which program did you use to do the benchmarks?

I'm going to try and see which change caused the slowdowns.

The built in benchmark tool inside msi afterburner.
