1167778 - X-Type game suffers from low frame rate

Status: RESOLVED WORKSFORME

(Core :: Graphics: CanvasWebGL, defect)

Description

Actual Results:
When playing X-Type in Firefox, after about stage 3 or 4 the framerate starts to suffer.  On stage 5 it starts to affect the gameplay.  Does not seem to be affected by e10s, enabling it might make the framerate slightly worse, but problem exists with it toggled off.  Chrome plays the game without framerate issues.

Expected Results:
Game should be smooth regardless of stage.

Steps to Recreate:
1 Navigate to the X-Type game
2 Start playing, notice framerate and how the ships stream of fire looks.  Observe responsiveness of ship.
3 Play well and get to level 5
4 Observe how the framerate is with all the bullets on screen.  Verify the ship is less responsive and stream of fire looks static because of framerate drop.

Severe frame rate issues once user reaches level 10+

Thanks guys, can you check if this bug happens in Firefox 38 or earlier?

For comment 4.

Bug still occurs. 

Special notes:

Once I got to level 5 the enemy craft disappeared and the player's craft moved to the left hand part of the screen flashing and jumping to random locations. This stopped after about 10 seconds and I was able to fly around without any enemies. After about a minute, the enemy finally reappeared and killed instantly causing Game Over.

Fully accelerated, but a 512mb card and fairly old driver.  I'm not sure how much we should prioritize this.

This bug is getting closer to being fixed. The issue I experienced above no longer occurs however the performance of the game around level 5 and greater is significantly worse than in Chrome and IE, which handle the game pretty well. 

QA Confirmed: Not fixed

Thanks Trammel, could you let us know which hardware you reported these results with for reference?

Let me know if this is still a problem, but it's working fine for me!
