Iris F-15 Strike Eagle

Just picked up the Iris Simulations F-15E. Very nice model and detailing. Although like the Iris F-15C model the HUD is hard on frame rates. That can easily be fixed however.

First the Israeli F-15I Ra'am version

The regular E model flying from RAF Lakenheath in the UK

Mike,

I must say thank you, those shots really do my AI F-15 credit, if I do say so myself. HEHE.

Lovely mate, I may have to get it myself now.

Sure does! I may have a go at trying to get the paint on the Iris model to look a bit closer to the paint on yours. Makes for better screen shots.

I've just got the bird. How do you correct the HUD FPS problem?

TIA

John it involves swaping out the hud image that comes with the Iris bird for the hud image that came with the Coral F-15. The Coral hud is more simplistic and therefore less taxing on your system performance.

When I got the F-15C from Iris, at first the frame rates were, well to put it bluntly, unplayable. I was getting less than 10 fps when using that model. It's heads up display was fairly complex, very close to the real thing I guess. Which is very cool but not at the expense of not being able to enjoy the model. So I did some searching around and found that I was not the only one who was having issues with frame rates. The "fix" was to swap the HUD out for something less complex.

When I fired up this E model last night, same thing, poor FPS. So I'm going to do the same thing again I think.

To do it follow this procedure:

This is my HUD mod to the Iris F-15 using the Coral HUD gage. I get very good frame rates from the HUD mod.

To use this mod you will need to have the Coral F-15 gauges loaded from the Coral F-15V2 pack.

First the panel config lines.

In the panel config section under [Window00], you need to add this line to the gauge list cut & paste) This is for the 2D panel HUD.
gauge36=F15_Gauges!AP_Alt Hold, 40,814,14,14
gauge37=F15_Gauges!AP_IAS Hold, 40,733,14,14
gauge38=f-15coral_v2!hud_swap, 424,98,201,268 <---"This is the line you need to add/use"
gauge39=F15_Gauges!Color-Power, 423,596,29,26
gauge40=F15_Gauges!HUD Cage Switch, 433,549,18,21

or just cut & paste this line next to gauge 38: f-15coral_v2!hud_swap

That takes care of the 2D panel HUD

Now the VC.
[Vcockpit01]
Background_color=0,0,0 size_mm=1024,1024
visible=0
pixel_size=1024,1024
texture=$vc_hud

gauge00=f-15coral_v2!hud_swap, 198,0,734,580 <---Cut & paste this line
gauge01=F15_Gauges!Effect Controller, 1,1,20,20

That takes care of the 2D & VC panel config change to get the Coral HUD to show up.

A couple of notes. I had to tweak the position of my HUD to get it centered & have the HUD horizon line higher on the eyepoint. On the ground, the horizon line is slightly low but in the air it is pretty much where it needs to be. Some of you who decide to use this mod may have to tweak the position of the HUD to get it to show up in the right position. Hopefully my mod lines will work just cutting & paste them in your panel config.

So that's the mod which also worked very well for me for the C model. I'll try later to swap it on the E model and check the results.

How does the model fly? I have consider purchasing it but can't seem to make myself spend the $30.

MIKE JG · Post by **MIKE JG** » 03 Aug 2007, 03:28

It handles well. About the same as the Iris F-15C model if you already have that. As with most payware in this price range, it has its shortcomings of course. But nothing that I would consider to be a negative. It handles very similar to the KO F-16 series if that helps.

You could always get the 'lite' version which is a lot cheaper. Only one visual model but it's a saving.

Once you get a taste, you'll be back for the whole thing. Trust me, I have both the full F-15E and the F-15C/D package.

I haven't tried the Coral hud swap. I may have to try that.

hi
i have the iris F15/E/SG/J package's and they are superb model's the only grip i have for my $30 is that the afterburner is activated with the light switch 'L' ? or have i missed summit ?.......i also have the iris F_35 JFS, Mig 27 Flogger, Mig 29 Fulcrum, and my fav the Phant FGR2 all have burners on the throttle.

just saying is all, remember wings level !

Jumpshot724 · Post by **Jumpshot724** » 21 Mar 2008, 20:20

I have the IRIS F-15A/C/D package, the way I fixed the fps was just to drop the VC detail level to low, since i never use the VC anyway. That fixed it perfectly.

The only problem I have is that the GPS button doesn't work, no way to see where you are which is very frustrating lol. I can only stay where I know the topography (and thus only in VFR).

The F-15E package ABs are activated with the lights? That seems weird since in the A/C/D it's automatic with the throttle input. Wonder why they did that....?

Gents,
I also have the both the E and C/D models. The reheat/afterburner works just the same in both for me ie as per the throttle. So not sure why you are having that prob.
Have you tried their forums ?

As i say mine works just fine.
Regards

Off-topic, but could someone tell me where the difference reheat/afterburner is? Is the first one british english and the second one american english? I remember working on the Tornado we used "reheat" but when it came to american aircrafts we used "afterburner".

GrahamS · Post by **GrahamS** » 22 Mar 2008, 17:24

They are both the same thing Jan, you are quite correct about the language thing, I'm just not sure which came from which side of the pond. I think reheat may have been the earleir term.

sprocky · Post by **sprocky** » 22 Mar 2008, 17:44

Thanks, Graham, could not believe that there was a technical difference.

Fastair · Post by **Fastair** » 22 Mar 2008, 18:43

Indeed correct, sorry for the confusion. Reheat is a British term, I simply added afterburner, after taking into account the multi-national members of this great site.

Regards,

sprocky · Post by **sprocky** » 22 Mar 2008, 18:55

There is no need for feeling sorry. I have been asking this question many times myself. As you used both expressions I thought it was time to ask here. But thanks for clearing that up anyway
