Hi all,
I have comeback to a project that I banged together some years ago now;
After numerous h/w upgrades, this code is still only hitting 60 fps.
At the time I thought that this was the hardware limit! GeForce2 (without asm)
(Although; running on win 98 SE has 25% speed increase over Win XP)
As this is quite unsettling. I would like some suggestion as to why this FPS is still unchanged.
FPS Code:
static float fps = 0.0f;
static float previousTime = 0.0f;
static char strFPS[20] = {0};
float currentTime = (GetTickCount() * 0.001f);
++fps; // Increment the FPS counter
if( currentTime - previousTime > 1.0f )
{
previousTime = currentTime;
//g_Log->printf(LOG_WARNING,"FPS: %d", int(fps));
sprintf(strFPS, "FPS: %d", int(fps));
SetWindowText(Main->hWnd, strFPS);
fps = 0.0f;
}
Set Camera
POINT mousePos;
int mid_x = wndWidth >> 1;
int mid_y = wndHeight >> 1;
float angle_y = 0.0f;
float angle_z = 0.0f;
GetCursorPos(&mousePos);
if( (mousePos.x == mid_x) && (mousePos.y == mid_y) ) return;
SetCursorPos(mid_x, mid_y);
angle_y = (float)( (mid_x - mousePos.x) ) / 1000;
angle_z = (float)( (mid_y - mousePos.y) ) / 1000;
mView.y += angle_z * 2;
if(mView.y > 3.5f) mView.y = 3.5f;
if(mView.y < 0.4f) mView.y = 0.4f;
Rotate_Position(-angle_y);
