B.5. MY FRAME RATE IS LOW 127<br />

3. Select <strong>the</strong> rightmost box next to joystick ail/elv/rud. This box will cause X-<strong>Plane</strong> to display<br />

<strong>the</strong> input it is receiving while running <strong>the</strong> simulation.<br />

4. Close <strong>the</strong> Data Input & Output window.<br />

5. A box in <strong>the</strong> upper right should be displaying <strong>the</strong> elev, ailrn, and ruddr <strong>com</strong>mands (elevator,<br />

aileron, rudder, respectively) being received from <strong>the</strong> joystick.<br />

6. Now, center <strong>the</strong> stick and pedals. Each axis should indicate 0.0, or close to it.<br />

7. Move <strong>the</strong> stick full left. The ailrn should indicate -1.0 or near -1.0.<br />

8. Move <strong>the</strong> stick full right. The ailrn should indicate 1.0 or near 1.0.<br />

9. Move <strong>the</strong> stick full aft. The elev should indicate 1.0 or near 1.0.<br />

<strong>10</strong>. Move <strong>the</strong> stick full forward. The elev should indicate -1.0 or near -1.0.<br />

11. Move <strong>the</strong> rudder full left. The ruddr should indicate -1.0 or near -1.0.<br />

12. Move <strong>the</strong> rudder full right. The ruddr should indicate 1.0 or near 1.0.<br />

By moving <strong>the</strong> stick and pedals and seeing what values <strong>the</strong>y are sending X-<strong>Plane</strong>, you can see<br />

if X-<strong>Plane</strong> is getting proper stick input.<br />

If <strong>the</strong> correct values (according to <strong>the</strong> tests above) are not being received in X-<strong>Plane</strong>, and you<br />

have calibrated <strong>the</strong> controls in X-<strong>Plane</strong> per <strong>the</strong> section “Calibrating <strong>the</strong> Hardware” of Chapter 4,<br />

<strong>the</strong>n <strong>the</strong> issue is with <strong>the</strong> hardware’s calibration in your operating system, not X-<strong>Plane</strong>. If <strong>the</strong> hardware<br />

is indeed calibrated correctly in <strong>the</strong> operating system, <strong>the</strong> hardware itself is malfunctioning.<br />

On <strong>the</strong> o<strong>the</strong>r hand, if <strong>the</strong> correct values from <strong>the</strong> above tests are being received, <strong>the</strong>n <strong>the</strong> hardware<br />

is working fine.<br />

B.5 My Frame Rate is Low<br />

For a step-by-step guide to increasing frame rate, see <strong>the</strong> section “Setting <strong>the</strong> Rendering Options<br />

for Best Performance” of Chapter 4.<br />

B.6 My PC Freezes after Running X-<strong>Plane</strong> Awhile<br />

When a <strong>com</strong>puter freezes after running X-<strong>Plane</strong> for awhile, <strong>the</strong> problem is almost always heat<br />

related. When <strong>the</strong> system is running X-<strong>Plane</strong>, <strong>the</strong> video card and processor get very hot because<br />

<strong>the</strong>y are running at <strong>10</strong>0% utilization. This causes <strong>the</strong> temperature to rise inside <strong>the</strong> case. To<br />

eliminate heat as an issue, remove <strong>the</strong> <strong>com</strong>puter’s cover and aim a fan into <strong>the</strong> case. Run X-<strong>Plane</strong><br />

for a while and see if <strong>the</strong> problem goes away. If it does, <strong>the</strong>n you need to add some additional<br />

cooling.<br />

Note that this assumes that <strong>the</strong> system has enough RAM. Running out of RAM will cause<br />

crashes as well. At least 2 GB of RAM should be used for current versions of X-<strong>Plane</strong>. This also<br />

assumes that <strong>the</strong> <strong>com</strong>puter is not overclocked.
