Guys guys guys thanks for all of your comments and advice!
These days I ve had a small communication (and a ticket) with Thrustmaster support. After explaining my issue they were positive that the problem is by the console and of course gt7.
They prompt me to try cleaning the PS5 cache memory on safe mode. I did what they asked for and also I did a database rebuild... for good measures 😛
Crossed fingers and tried on gt7 on the beloved last mission of the sun also rises in Bathurst and well... Can't say for sure maybe there was some placebo effect kicking in but it felt a tiny bit better. At least more bumpy and shaky. Maybe a little stronger too.
The stupid rubble when turning hard (instead of actual FFB) is still there pissing me of all the time. So no big deal but maybe something. Will try it out further when I have the time.
Then I decided to try once more on Dirt Rally 2.0 and.... Holy Sssmokes!
SSsS just got real!! I don't know if it is the older car that I used or maybe that some of the assists were off but omG!
This thing is HEAVY! I turned it down by the half of it and it is still pretty heavy!
That thing is bumpy! Literally my stand is shaking!
If I get a little bit off road I feel nasty things going on...
Even tried out tuning the FFB settings of the game from a guide suggesting to lower everything pretty much and still I feel like I am in a rally car struggling to keep it in a straight line. And for me that's brilliant!
Definitely not the wheel's fault, that thing is not a toy. It's dumb development of gt7 making this major piece of equipment feel like a toy.
They probably messed everything up when they tried to readjust them physics for rear drive cars. Fixed one thing, screwed 5 others up.
I get a feeling for most major game devs lately, it's like they all have a race on who will destroy and mess up their game first!
Incredible really that in 2022 and in the age of PS5 we don't have a decent football game and a decent Gran Turismo.
Polyphony , literally all these 5 6 7 years I don't know ... You had one job!
Excuse me for the massive comment men, I have just reached to many conclusions
One advice, its not recommended to put FFB at max values for this wheel.
T300 have arround 3nm/5nm of torque.
what will happen if you constatly drive using FFB at max is clipping wich means youll not receive correct feedback, electric motors from the wheel will start to get hot and butter feeling and eventually youll kill them.
In assetto Corsa competizione ingame FFB i use arround 75 max 80/85 in FFB value.
In GT Sport i used FFB between 3 and 5, 5 being already to much for this wheel.
I always found the FFB decent at those values.
I didnt tried it yet on GT7 cause my Ps5 only arrives today, but been reading all the news from GT7 seems they updated the physics and lowered FFB strengh.
A good game to test how far you can go with that wheel its Raceroom, you can go to options and check the recomendations, and you can also pull a small graph so when you driving you see the FFB output in real time.
In raceroom you have to configure FFB to each individual car, you also can configure keybinds to lower and increase FFB strengh in real time while you see the graphic.
You must configure it to always be lower to the limit upper line in the graph, its a good way to feel how far you can go with FFb forces in other games.
Assetto Corsa Competizione you also have a way to see if you pushing to much on the FFB, in the bottom Right of the screen theres a small bar that shows FFB working, if that bar its hiting red values all the time you must lower the FFB strengh until its grey and when forces kick in the bar should be near grey/red limit but never red all the time, some tracks it might hit red but it must be very situational or almost never happen.
Anyway soon i will test my t300 on GT7.
