Introduce Lite textures for the following files.


This will improve the game performance dramatically, as much lower memories are needed to load this file,
this in turn will increase FPS for those struggling with the game, even if you got a uber rig, u can still
be benefited by a more smoother experience.

Just try switching those corresponding files with ArmA 2 and ArmA 2 Free, you will notice an immediate
performance increase, yet the graphics still look as good as before, as those files you switched are used
extensively for the gameworld, yet people never tend to take notice of them, so why have the quality of them so high??

You can do this on your own (if you can play on a server without signature system). See:

Overall there generic solution would a video option to force a lower / a specific maximum texture resolution.

Updated by sapped almost 4 years ago

yeah, but the important thing is that most server will reject this as they require signature check
like you have mentioned, alot of people play ArmA for the multiplayer, as it contains the kind of realistic military
experience unlike anything on the market, so something like this will HAVE to come from the devs

lowering texture resolution ingame doesn't offer much in terms of performance, everything still looks
nearly identical as before. and not even close to the amount of FPS gain by using lower quality plants/rocks etc.
which people hardly cares about or even notices.

so having the devs to set up the lite quality files and make them acceptable for signature checks
is the only way to do this.

btw, thx for the suggestion u gave me about this awesome tweak before!!

Don't get me wrong. I am using A2F myself for a CO lite.

However to have it configurable rather than to have two different distro would be the real solution.
That said the question is if that can be done as video option.

Maybe the PBO size / the texture size (in RAM/VRAM) / no quick resolution conversion/reduction possible is the problem.

Yet if the engine could determine/limit the texture resolution to be sent to the GPU dynamically,
it would be the way to go IMO.

Isn't that already occuring when you set Texture Quality / Video Memory to say, Low?
AFAIK engine loads/caches files from the pbos, not the pbos themselves.

This will improve the game performance dramatically,

Are you sure about this? Is there some experiment one can run to confirm this? I have implemented emulated "lite" textures ingame to avoid having to repack the data, but I was unable to find a scene in which it would help significantly.

Just try switching those corresponding files with ArmA 2 and ArmA 2 Free, you will notice an immediate performance increase,

Please, attach a scene (preferable as a repro mission) in which you can see the increase.

Suma you find FPS comparisons in the PvPscene Benchmark Suite spreadsheet - line 43 - 51:

Note that the comparions is based on a rather old 1.60 beta.

Basically it shows a 5 to 20% improvement of average FPS.
Even more for average minimum FPS (up to 30%).
