DUST Search - I fixed aiming.

So... my GIMX parts have arrived. I did a quick test today.

Results are amazing. Basically I've fixed the virtual joystick problem (completely bypassing CCP's virtual joystick and simulate our own DS3 controller) and now it feels like an almost linear input and zero acceleration. The only problem remain is the native speed limit of the DS3 analogue stick (at in-game settings 100%). If you move your mouse too fast you will hit the speed limit which feels awkward. The precision needed some tweaking (deadzone settings etc). Also the framerates can present a challenge to aiming, but in general aiming is much more predictable and there is much less weird magnetic feelings. But without much tweaking it already feels so much better than the native kb/m support. This thing's USB runs at 250hz too! (Compared to the native 100hz)

The keyboard mapping needs some time getting used to since it is now simulating the DS3. The shift key (L3) also toggles sprint which is a bit weird.

Parts. Top right: An ATMEGA32U2 board from Canada (NooElec brand). Bottom left: A bunch of unbranded CP2102 USB to serial boards from China. The seller sent me several by mistake, I just needed one.

Soldering up.

Testing. The instructions were wrong and I had to swap two wires to make it work.

Put on some protective nanites and we are done.

GIMX in action. To the left is my laptop (USB), to the right is mini-usb to PS3 (same cable as DS3 controller).

This is what the settings look like in Windows.

Mouse sensitivites.

What it looks like in-action. All your inputs (keyboard and mouse) will be sent to the PS3 as simulated DS3 controller signals.

Can't say my kd ratio has improved yet but I'm having fun playing with it. I can also dance around corners and toy with enemies with much more accuracy. It's nowhere near perfection, it is only as good as a DS3 controller can get. I need more time tweaking but I think I've already fixed the game to some extent.

You're trying to have an advantage over the already advantage of KB/M over DS3. I am just using the computer to control a DS3 controller so I gain no advantage over DS3 controllers.
5aEKUXeRJGJ27kCDnDVYak4 Expert Intervention Caldari State 59	Posted - 2013.07.03 19:58:00 - [3] - Quote After extensive testing, I can confirm that CCP's DS3 aiming is broken. It is not acceleration, it is not smoothing, it is not aim assist, it is PURE JITTER is being introduced into the aiming. In the GIMX there is a calibration mode which simulates a set of inputs to test if the game is responding as predicted. It can repeat a series of sweeps of set distances (slowly turn left x amount, quickly turn right x amount) for observation so there is unmistakable that the issue is not in the player or DS3 controller. When I run the test, when in theory moving left X and moving right X (EXACTLY the same amount) should end in the same position, the game will turn the aim either not enough or too much. This is not related to acceleration, sweeps with different speeds were mixed together and the aim do not solely overshoot/undershoot (which would indicate acceleration) but it jitters back and forth. This is done with aiming assist turned off. This is not related to hardware issues either because different USB polling rates and simulation modes are all tested. It means Dust 514's aiming somehow introduces RANDOMNESS into your movement from absolutely nowhere and there is no way to eliminate it. This is a very bad news. Because this proves that Dust 514's aiming has inherited Unreal Engine 3's poor design - aiming cursor movements depend on frames (framerate). And it means that THIS GAME IS NOT FIXABLE because of the engine it uses. A very sad but undeniable truth which will deny any future potential for Dust to become an e-sport. There, CCP I've done the work for you. You don't have to mess with your sensitivities anymore, the problem is not there.

What is CCP's policy on people using obviously modded hardware, and then advertising it on the forums? Just wondering. This is legal. Are you aware of the commercially available Eagle Eye adaptors? The GIMX does exactly the same thing. It is nothing more than an adaptor.

To the game (in fact, to PS3 itself) I have simply plugged in a DS3 controller. The PS3 doesn't even know I am using an adaptor. It is not detectable even if a GM were to watch me playing because my movements will fully comply with the specifications of what the DS3 controller can do. In short, it does not matter if it is legal or illegal, it is invisible.

The same discrete accumulation affects polling rate. Wat?! Are you sure the input processing is frame-rate-dependent? I think I misunderstood you, but are you saying that the input behavior is different when looking at someone standing in front of flaming wreckage than it is when looking the other way? Please, be a nice dev and tell me that all input handling regardless of input device is done at 100 Hz outside the graphics thread based on the best timer the PS3 has available. Please. NEGATIVE

Not about the jargen I mean I don't feel my aiming is off. At best I can say there have been a few sniper rounds that made me think, "I swear that should have hit that guy" but nothing to suggest aiming is broken altogether. I can still turn and shoot a dude in the face. What is the problen? It's ok. Not everybody has to be able to feel it for it to be broken.
