FPS problem

It is definitely being limited by the monitor refresh rate.

Turn off vsync.

There is an option to turn vsync off/on in your opengl nvidia settings found in your disply settings

As far as I know, I don''t think it is possible to turn off vsync, in OpenGL, in code... Your manufacturer usually lets you turn it on/off manually somehow...

What I do:

1. Right click on the desktop
2. Choose properties
3. Go to the settings tab
4. Click on advanced
5. Go to the 3D settings
6. Click on the checkbox for disable VSync...

I think most cards can do something similar...

It''s simply not possible in standard GL.

There''s a WGL extension for that. It''s called WGL_EXT_swap_control.

Now, don''t fear the thing it''s WGL. Checking for WGL extensions is a bit more complicated but getting ext pointers is as easy as it is with other ext.

More on this if you are interested.

Thx, i found it under settings. Besides, i just want to see 100+fps during development. So now, whenever i add something new to my engine or draw something new, ill noe how much it affects the framerate.

Also, no matter how fast ur system, it will always be displaying at the rate at which ur monitor supports.So Vsync is actually good.

"Also, no matter how fast ur system, it will always be displaying at the rate at which ur monitor supports.So Vsync is actually good."
I don''t get the point in this however, in my opinion vsync is a horrible thing while developing.

Some days ago I did a thing which resulted in a 84fps slowdown on a 85hz display. With vsync off i notices it was, in fact a 200fps slowdown. Quite different.

Now, the thing was very stupid but I am going to leave vsync off during devel. Limitating vid card power is bad because it hides your pipe optimizations if you are doing some and does not show you what''s the best between two render paths for example.

If you want to turn it on/off every time it''s up to you but I personally think the vsync thing must be handled with care and definetly turned off while developing / benchmarking.

Oh, well not sure, on this however, it''s a personal opinion.
Excuse me if I have misunderstood you post. Sorry!

It''s not a very good way to make your game run at an equal pace. For one thing, other computer may be slower and run at 80 fps so this doesn''t guarantee that all games run at an equal pace.

To do that, there are several methods and varying levels of complexities should you wish to implement them.

Half-life scales back on textures when running on a lousy graphics card. This auto scaling feature works great to acheive higher frame rates on less powerful systems. Plus you can implement this for other systems, like play less ambient music or something like that.

To lock down framerates, you can use the sleep function, though that is a waste of time if you use it just like that. Some people suggest that you calculate the amount of time to sleep from the amount of time spent and then sleep for that duration.

In order not to be wasting CPU cycles, you can implement your input and networking modules in seperate threads, which don''t require that they follow the framerate.
