[1.18 Hotfix 1] Focus on FPS Gain and Loading Bug (Memory leak?)

Post by Loran_69 »

Sorry, didn't realize we have a specific Beta Forum to post feedbacks. Please feel free to move my post, thanks.

First feedback for 1.18 Beta

I focused only on FPS gain. So before applying the beta program I loaded version 1.17 with the showfps flag and checked fps of my first 5 savegames, made with my ship standing at different place, and waiting for a stabilization (around 1 minutes). I did that by staying in the game each time. Here the result :
29
42
50
30
44

Then I applied the Beta patch 1.18 and saw this (second numbers, first are copy of 1.17) :
29 / 31
42 / 49
50 / 35
30 / 15
44 / 7

So I understood something get wrong each time I loaded a game. So I made the same test this time exiting fully the game, going back to Steam, waiting for the cloud Synchronization (doing nothing as I didn't save) and relaunching. This process between each reload, and here the result (third number, first 2 are copy of previous test) :

29 / 31 / 31
42 / 49 / 51
50 / 35 / 60
30 / 15 / 41
44 / 7 / 53

So 2 (obvious) remarks :

1/ Bad: Something get wrong each time we reload a game (memory leak, etc.) when we stay in the game.
29 => 31
42 => 49
50 => 35
30 => 15
44 => 7

1/ Good: if we take apart the loading bug, Nice fps improvement, Congrats Team! :)
29 => 31
42 => 51
50 => 60
30 => 41
44 => 53


This evening I will test other fixes.

Anyway, thanks so far for your work !:)

How do you enable the showfps flag?

i can confirm this problem on 1.17 too,
first start of x-rebirth (and load into game ofc) consumes ~ 2gb of ram, gpu running at 97%, 50 fps very smooth.
after few alt+tab and reload the game -> no chance to move anything, 4-6fps 5-10% gpu (seems to be throttled by x-rebirth), same cpu usage, ~ 4gb ram usage.
seems to be memoryleak (@Dev: write a garbage collector).

btw: how did you got 1.18b patch? my steam said there is no new patch.

To be part of the beta testing and get 1.18:

I didn't have this fps going down problem when loading several savegames in 1.17, and for me this is new from 1.18 I'm pretty sure about this.

For the showfps flag: in Steam, right click on X Rebirth, Properties, and in English it should be something like "Define lauch option" or something similar (I have it in French). Now type "-showfps" without quotes, and you'll see fps bottom right during game.
