with a 1ghz processor and half a gig of ram.. is it faster if the Card does the T&L or will it slow things down???
P.S. sith where is our hardware section?
Of course it will speed things up. T&L just does the, uh, Transform and Lighting, which your processor would have had to do in the first place. I noticed a nice bump up in speed when I enabled it. Go do it now.
When T&L is enabled on my P3 800MHz it slows down. My processor can handle it better when its switched off
Wierd. It really shouldn't.
I'm running a 1Ghz TB and as I said, it made a pleasant difference.
In theory you'd expect it to be faster, but with a fast CPU on a simple mission the CPU may have enough free time to do the T&L calculations faster than an older graphics card... whereas on complex missions the card can offload that work so the CPU has more time for all those AI calculations. I've also seen even brand new machines shipped without AGP4x enabled, and if you're running with a slow bus with geometry data in host memory then the card simply won't be able to read the geometry data fast enough.
So I'd expect this to run faster, but it will depend on the precise configuration of your machine, and the complexity of the missions you play: really you need to try both and see.
OK, ive looked around on the net and basically what ive seen is that apparentley the HW T&L might slow your computer down... basically if your computer is fast enough to where your graphics card is the bottleneck.. hardware T&L will make it WORSE.. if however your processor is the bottleneck the T&L will make it faster...
basically it matters how "used" the card is.. if you have a super fast processor.. faster than your card can fully utilize, making the card do MORE work (HW T&L) will make it even works and slow things down.
but if your Processor isnt fast enough to push your card to its limits then using HW T&L will make it faster because its taking some strain off yor processor with is being used to its max and shifting it to your card which has power to spare..
makes sense to me..
and as for as ive read this change seems to take place around 1.1ghz with the GF2 ULTRA.. but I have the Ti so its probably like 1.05... so in my case I doubt there would be much difference because my system is pretty balenced.. the card and processor can fully take advantage of each other...

Just out of curiosity, have you OC'd your CPU? I'm assuming it's AMD?
If someone reports an issue/complains about the Alpha etc, replying in the thread "dude it's an alpha" doesn't really help anyone! Point them to the Arma3 Alpha feedback tracker instead please!
Please do not PM or Email me directly about your CD Key issues, follow the guidance in this thread instead.

I'm starting to think HWT&L slows my machine down somewhat. It would seem to make sense after what you've said.
I have a P3 850 w/ GF2mx and possibly the card is too slow for the CPU thus the bottleneck is the GFX card. I think I shall perform some benchmark tests.

I have AGP4x disabled on my computer and I don't see any degrade on performance compared to AGP4x enabled. It's only more stable when it's disabled. And I have a relatively old computer (Athlon Classic 750Mhz, Geforce 2 GTS).
I would like to know what exactly does the AGP driving value do and what kind of machines have a performance boost when it's enabled.
