Not that anyone here these days ever uses arcade mode.
But in the interest of helping beginners who might make use of this game option...
As you know, in the [game] section of conf.ini is the entry
Arcade=0
When set to 1 this enables three visual aids:
- For bullet hits against other than aircraft, a glowing blob is drawn at the hit point.
- For hits against aircraft, a bunch of arrows are drawn passing through the craft to indicate the direction of travel of shrapnel particles generated by an explosive round.
- For certain aircraft events like a gunner being hit, a fire commencing, bailing out or the decision to RTB, a 'thought bubble' with the appropriate phrase appears just above the plane for a short while.
I've just begun exploring this because the crucial Explosions.class invokes two of these features; hit blobs and 'thought bubbles.'
-----
The hit blobs are generated by method generateShot(), and in the stock implementation are kept active for 30(!) seconds. Because I've increased the live times for most bullets by a factor of 2-3 (only some cannon shells required to increase their live time), the chance of hits against the surface and objects is increased at lower altitudes. This can result in quite a lot of these glowing blobs being scattered all over the landscape if the visibility distance of the texture is on the larger side (10km seems to be the stock value.) And this can impact frame rates.
My inclination is to stop the drawing of these glowing blobs entirely. Who needs to see where their shot has impacted after the event? Least of all for 30(!) seconds. As an alternative I could shorten the live time of these blobs considerably, to, say, 3 seconds. And to make the texture smaller and/or less opaque and/or of a different form.
-----
The thought bubbles were made fully opaque, and they were drawn so as to hide part or much of the plane, impairing the ability to see in order to aim for subsequent fire. I've made them partially transparent, as well as continuing to shrink beyond the former 100m limit out to the new limit of 500m. These measures make these 'thought bubbles' FAR less obstructive.
