Whats Causing the slow down in this code?
« on: October 25, 2018, 11:24:10 am »
So I've started my next project of bringing another of my old QB45 games up to QB64 and I'm encountering a problem right off the bat.
The code that displays the enemy ship slows way down. on my antiquated machine I start out around 110 cycles a second, but when it starts to display the ship graphics the number plummets down to the mid to upper 30s, that is nearly a loss of 70-75% cycle speed! and that is all this code does, I haven't even started with the AI logic for this ship to shoot at the player or any of the players side! It ran just find in QB45 with DirectQB no speed issues then with all the code working. So what is causing the major performance hit now? I've tried to cut off anything that doesn't display on screen so its not wasting time there but does not seemed to have helped.

Code: QB64: [Select]

odd, Select all didn't get it?

SUB ClearLayer (id%%)
 old& = _DEST
 _DEST Layer(id%%)
 CLS
 _DEST old&
END SUB

 (added it to the code above too.)

I don't see anything to blame at a first glance. _DELAY inside a DO/LOOP doesn't look like the best way to go (_LIMIT, maybe?), but it shouldn't delay more than what it's instructed to anyway.

Hope the issue emerges soon so you can proceed.

_delay is just there to control CPU usage. when I remove it , I start 190ish cycles and drop down to mid 40s which I think is even worse than having the delay! gain nearly 80(72% gain) cycles on the max and only only about 10(29% gain) on the lower.

This is the first time I've experienced any kind of issue with speed in involving the graphics in QB64.

Simplified some of the math, moved some of it outside the loop, and replaced the _DELAY with a _LIMIT, which performs much better on my system.  I'm holding steady at 120FPS now, but don't know what performance you might expect to see on an older system.

Afraid not, only gaining about 7(average) cycles but uh, take a look at the graphics being outputted.

And, if you can't get the FPS up to the speed that you expect for your game to operate properly, you may need to change the step that the ships move to keep the game flow consistent, such as something like this:

Note that this has a HUGE set delay of .1 seconds per cycle (compared to your original of 0.005, it's 20 times slower), and the ships still scroll right to left at around the same speed -- they're just moving in "chunks" now, as they skip several draws, but they're still advancing across the screen at the same rate.

Since you're only dropping from 110 to mid/upper 30s, that's a decrease of only about 1/3 for you, rather than the 1/20 which we see here, so that "step" isn't going to be as large and you're not going to notice the jerkiness as badly.

Honestly though, I'd go with a _LIMIT in this case, rather than a _DELAY.  Then, when the machine bogs down and needs more power for performance, it can use it, instead of having to wait no matter what.   ;)

(And I didn't pay attention to the background; I just was paying attention to the ship/arms.  Let me see what I did to the background...  :P)

Re: Whats Causing the slow down in this code?

If all else fails, you might need to skip some frames so the game continues to move at the same rate for you.  :)

Re: Whats Causing the slow down in this code?
« Reply #9 on: October 25, 2018, 01:31:28 pm »
After running this little test code, I may just increase the size of my sprite sheet, look at the speed differnce between the regular putimage and the putimage that zooms tests! that is a major hit. when you zoom with putimage you lose over 10x the speed. why would that be?

Code: QB64: [Select]
  1. SCREEN _NEWIMAGE(640, 480, 32)
  2. Layer&(0) = _LOADIMAGE("DFsprit8.bmp", 32) '  Sprite Layer
  3.  
  4. DIM testimage(1024) AS LONG
  5.  
  6. _DEST Layer&(0)
  7. GET (0, 0)-(15, 15), testimage()
  9. LOCATE 5, 1: PRINT "Test 1"
  10. start1! = TIMER
  12.  PUT (0, 0), testimage()
  13.  LINE (0, 0)-(15, 15), _RGB32(0, 0, 0), BF
  14.  cycle1& = cycle1& + 1
  15. LOOP UNTIL TIMER >= start1! + 5
  16.  
  17. PRINT "Test 2"
  18. start2! = TIMER
  20.  _PUTIMAGE (0, 0), Layer&(0), _DISPLAY, (0, 0)-(15, 15)
  21.  LINE (0, 0)-(15, 15), _RGB32(0, 0, 0), BF
  22.  cycle2& = cycle2& + 1
  23. LOOP UNTIL TIMER >= start2! + 5
  24.  
  25. PRINT "Test 3"
  26. start3! = TIMER
  28.  _PUTIMAGE (0, 0)-STEP(32, 32), Layer&(0), _DISPLAY, (0, 0)-(15, 15)
  29.  LINE (0, 0)-(32, 32), _RGB32(0, 0, 0), BF
  30.  cycle3& = cycle3& + 1
  31. LOOP UNTIL TIMER >= start3! + 5
  32.  
  33. PRINT "Put Test Cycles per second          :"; cycle1& / 5
  34. PRINT "PutImage Test Cycles per second     :"; cycle2& / 5
  35. PRINT "PutImage zoom Test Cycles per second:"; cycle3& / 5
  36.  
  37.  

I'm not overly sure how the play would be if things begin to get 'jumpy' while your trying to line up the small fighter to shoot or bomb the targets(ARMS) on the ship, that is my main concern there.

If you don't need alpha, try to add this command in there:  _DONTBLEND

By default, QB64 tries to blend images into the background, but if you don't need to, _DONTBLEND is a heckuva speed boost usually.

  6.  

You're doing a lot more work with the "zoom" print.  First, it's got to scale up your image to twice the size.  Then it's drawing to an area 4x the size.  (Twice as wide, Twice as tall).

Code has been cleaned up and math routines reduced as much as possible inside the graphic display portion, with no effect to display.  (WTH went wrong last time is beyond me.  Probably just something simple that I'm just too lazy to notice ATM.)

FPS counter has been replaced from a 1 second counter to a 1/10th second counter.
With this 1/10th counter, we now utilize a Limit% to set the maximum speed that we want the game to run.  On my PC, I've set the speed to 200 so I can watch the movement step in action.  A FPS of 120 or less doesn't require the movement to change at all now.

Changed the _PRINTSTRING to a lazy LOCATE and PRINT so that I could tag on some information without having to use my brain...  I imagine eventually they'll disappear completely once debugging is finished, so it shouldn't really matter.

Fixed _DELAY changed to variable _LIMIT for better use of maximum CPU power when the game needs it.

And added in a basic "skipframe" routine so that we maintain game speed even when the PC can't render all the graphics fast enough for us.  (Xstep!)  For me, the highest this step ever goes is to about 1.7 pixels instead of 1 pixel, so it's not a noticeable change at all.  Instead of the ship moving 1 pixel, 20 times in 1/10 of a second, to make 200 FPS, it ends up moving 1.7 pixels, 12 times in 1/10th of a seconds, to make 200 FPS, at its most taxed operation.

The change there just isn't very significant visually for me, but it keeps the game scrolling smoothly and without slowing down.
1 pixel, 20 times, in 1/10th of a second vs...
1.7 pixels, 12 times, in that same time frame...

And, if you think the game runs best at 100 FPS, then there's no change at all for us.  We'd run 1 pixel, 10 times, in 1/10 of a second, all the time.  (At least on my PC we would...)

It's the best solution I can think of for you, so the game can run smoothly on both older and newer machines.  ;)

By pre-drawing the ship, this runs at a nice little 520 FPS at the slowest part of execution (on my PC).

The only thing you'd want to do here is "erase" the weapons/engines/whatnot from the DNS image (or make a copy of the DNS image to use so you can erase from it), whenever the player destroys one of those weapons. 

Try it out, see if this might not be the way you'd want to go for the game.
