Author Topic: SDL->SFML conversion; very strange performance issues (Read 18467 times)

ChonDee · « **on:** January 17, 2012, 07:26:07 am »

Hi everyone,

As I have been browsing around about SDL, I saw SFML mentioned as a potentially better and more sophisticated API for certain purposes. I haven't had performance issues with my game in SDL yet, what made me try to convert to SFML is the scaling, rotation and some alpha blending features it has. Even though my game isn't crazy big, I have decided that I will first try to rewrite my very first working build, which I didn't divide to multiple cpp and header files yet, and was only about 1K lines.

After I have rewritten it successfully, and ran it in Debug (in Visual Studio 2010) I ran about 5FPS, or lower. After some searching around I saw it mentioned that the debug libraries are slower, I should use Release instead, so I did. When I ran that inside Visual Studio with F5 it was faster, but still unacceptable frame rate (60FPS is the target). When I just build an executable and run it outside VS it ran okay, but when I increased the particles drawn a bit, the performance dropped. When I compared the SDL build with the SFML build, the SDL one got better performance.

Since the SFML sample projects that I compiled with the exact same settings, in the same solution file ran with 1000+ FPS I have figured there must be something wrong with my code and I am probably misusing some expensive SFML calls.

Most of the game objects are added this way:

Code: [Select]


void World::explosion(int x, int y){
for (int i=0, r=((rand() % 100) -80); i < 120 + r ; i++){
int xx = x + rand() % 10 - 5;
int yy = y + rand() % 10 - 5;

Particle a(xx, yy, 6);
v_particles.push_back(a);
}

Every actual image is only loaded once, during the initialization, and every object only has a sprite associated with the image. The objects will be drawn later in the game loop.

Later I have discovered, that even if I don't draw the objects, don't use any SFML draw calls at all during the game loop, just have the c++ logic running, with vector.push_back loops, the frame rate drops drastically.

This would make me think that what I am doing is too expensive on the CPU, too many vector operations are going on, and this has nothing to do with SFML, but all this runs perfectly fine when I use SDL.

At this point I am not even sure what exactly to ask, or what information to provide. Is this something that has to do with my VS 2010 solution settings perhaps? How come the sample projects with the debug SFML library in visual studio (pong for example) runs 800+FPS, while my game only gets 1-5 with those settings?
I have removed event polling too and I have removed the clock to make sure I am not doing something bad with that, that would affect the frame rate.

It looks like that the c++ operations are the bottleneck, because the frame rate is the same even if I comment out the SFML draw lines, but with the exact same, unchanged logic, with the SDL solution and SDL calls runs just fine.

How should I try to tackle this problem, what do you guys think that causes this?
Let me know if you would need my settings, or parts of my code, or something

Thanks in advance

Here are the frame rates of the sample pong.cpp included with SFML, and with my project
All are compiled from the same VS 2010 solution file

pong | Debug configuration | Started with F5 (Start Debugging) : 130FPS
pong | Debug configuration | Started with CTRL + F5 (Start without Debugging) : 175 FPS
pong | Release configuration | Started with F5 (Start Debugging) : 700 FPS
pong | Release configuration | Started with CTRL + F5 (Start without Debugging) 1600 FPS

myGame | Debug configuration | Started with F5 (Start Debugging) : 0 FPS, didnt draw another frame for 20seconds
myGame | Debug configuration | Started with CTRL + F5 (Start without Debugging) : ~1 FPS
myGame | Release configuration | Started with F5 (Start Debugging) : 2-3 FPS
myGame | Release configuration | Started with CTRL + F5 (Start without Debugging) : 27 FPS

myGame with SDL calls, 60FPS fixed

Oh wow :shock:! That is a huge difference. I'm sure its something you are doing with SFML that is very expensive. The first thing I would do to tackle this is review your code and take things out until you figure out whats the bottleneck. If you can share some of the code we can probably find the problem.

Best of luck!

I have made an analysis with AMD CodeAnalyst for both the SDL and SFML implementation, and I have attached the relevant part of code that strains SFML, for both the SDL and SFML one.
Please take a look at it.

Thank you

This one is for the SFML code:

CS:EIP Symbol + Offset Timer samples
0xd33560 Particle::show 73.98
0xd31a70 Player::show_particles 13.12
0xd36150 std::_Remove_if<Particle *,bool (__cdecl*)(Particle)> 9.28
0xd37290 std::_Uninit_copy<Particle *,Particle *,std::allocator<Particle> > 0.9
0xd32800 World::show_stars 0.68
0xd36ed0 std::_Find_if<Star *,bool (__cdecl*)(Star)> 0.68
0xd363c0 std::_Remove_if<Star *,bool (__cdecl*)(Star)> 0.45
0xd32630 World::show_enemies 0.23
0xd32790 dead_s 0.23
0xd33410 Star::show 0.23
0xd34d60 main 0.23

11 functions, 82 instructions, Total: 442 samples, 100.00% of shown samples, 2.27% of total session samples

So the way I tested performance, since in this early version of my game there aren't many objects, I increased the particles coming out from the player's thruster (in both SDL and SFML, the same number)

In the SFML one it seems like this takes up everything.

Here is the code for Particle::show:

Code: [Select]


void Particle::show()
{
    //Show image
if (initialized == false){
if      (type == 1) part = p1;
else if (type == 2) part = p2;
else if (type == 3) part = p3;
else if (type == 4) part = p4;
else if (type == 5) part = bparticle;
else if (type == 6){
  if ((rand() % 4) == 0)
  part = p1;
  else if ((rand() % 4) == 1)
  part = p2;
  else if ((rand() % 4) == 2)
  part = p3;
  else if ((rand() % 4) == 1)
  part = p4;}
initialized = true;
}

    if(alive)
{
part.SetPosition(x,y);
App.Draw(part);

//apply_surface( x, y, part, screen );
    }

    //Animate
//stuff here is not relevant, and its exactly the same in both

I'll put the same code here for SDL for comparison, so you won't have to scroll back and forth.

Code: [Select]


void Particle::show()
{
    //Show image
if (part == NULL){
if      (type == 1) part = p1;
else if (type == 2) part = p2;
else if (type == 3) part = p3;
else if (type == 4) part = p4;
else if (type == 5) part = bparticle;
else if (type == 6){
  if ((rand() % 4) == 0)
  part = p1;
  else if ((rand() % 4) == 1)
  part = p2;
  else if ((rand() % 4) == 2)
  part = p3;
  else if ((rand() % 4) == 1)
  part = p4;}
}

    if(alive)
apply_surface( x, y, part, screen );
  
    //Animate

And CodeAnalyst result for the SDL code, Particle::show doesn't strain it as much at all

What version of SFML are you using? What class is 'part'? That code seems fine to me. What happens if you comment out?

Code: [Select]


part.SetPosition(x,y); 
App.Draw(part);

EDIT:
Could you give the full class of Particle?

sf::Sprite part;

Also, I commented the 2 lines out, so they aren't drawn here are the results

11 functions, 130 instructions, Total: 632 samples, 100.00% of shown samples, 2.49% of total session samples

So it still takes up most of the resources, without drawing the particles.

Here is the full particle class (without its methods)

Code: [Select]

class Particle
{
    private:
    //Offsets
    int x, y, xVel, yVel, type, life;  //type 1 to 4 fire, 5 laser, 6 explosion

    //Current frame of animation
    //int frame;

    //Type of particle
    sf::Sprite part;
	bool initialized;
	

    public:
    //Constructor
    Particle( int X, int Y, int Type );

    //Shows the particle
    void show();

    //Checks if particle is dead
    bool alive;
	bool vel_set;
	//bool dead();
};

Same with the SDL implementation, only there part is not sf::Sprite, but a pointer to a SDL_Surface

That seems fine to me also. You got something messed up somewhere

Quote

Later I have discovered, that even if I don't draw the objects, don't use any SFML draw calls at all during the game loop, just have the c++ logic running, with vector.push_back loops, the frame rate drops drastically.

The Particle class is actually being copied when its being pushed back. However I don't think that is why that would drop the frames.

Can you show me your main game loop? Can you also show the World?

I'm determined to find this >.<!

p.s. If you want you could just upload all of the code lol

Thanks for your help

I might have probably messed up, or doing stuff unoptimized, or whatever, what my concern is that the EXACT SAME code is running with the SDL version only with different display calls, (which I even commented out in SFML) and it runs fine and fast in my SDL solution, and runs really bad in the SFML one.

I am starting to think that it might be something to do with the VS configuration...

I'll upload the code for both versions, but be warned, it's quite messy here and there, as that was the earliest version of my project

No problem. I got nothing else to do at this time.. I can't sleep lol. Anyways you can upload the visual studio project with it make my job easier on figuring out whats up with it. Are you using SFML 1.6 or 2.0?

Here's the SFML version's code:
to make things easier you could just comment out everything other than show world, or show player, it will be just the same.

Thanks, I'll upload the VS solution!

Alright, here is the solution file

BTW I am using SFML 1.6

Maybe you could post a minimal (yet still complete) code that reproduces the problem?

Try SFML 2, you'll get a huge performance boost if you use the same image for all your particles.

ChonDee · « **Reply #12 on:** January 17, 2012, 09:14:40 am »

Thank you for your comment, I'll try to replicate the problem somehow.
So far I don't quite understand it either, other than the same code runs faster in my SDL VS2010 project than in the SFML project, even if I don't even make the SFML display calls.

As soon as I figured out what causes this, I will switch to SFML 2, since I will be using a lot of particles and objects sharing the same sprites.

Okay so I changed the TOTAL_PARTICLES to 80. I think 1000 was way too much. I built it in release mode and it had no problem running at all. Is there a reason why you had the number so high?

With that number being 1000 you would be creating 875 particles per frame in the Player::show_particles() function alone! With it being 80 its only creating 70. Assuming I understood your code correctly

Yes, there is

So the way I tested performance, since in this early version of my game there aren't many objects, I increased the particles coming out from the player's thruster (in both SDL and SFML, the same number)

Before I would rewrite my current progress, which is bigger than this early build, I wanted to be able to see how it would perform.

And it just bothers me so much that the particles stress the SMFL project much more, even without having them drawn, than the sdl one..
