I have a csw 2.5 and play GT7 on PS5 with a drivehub with the fanatec native mode (don't use fanalogic it's terrible)
These are my settings:
SEN Auto
FF 100
SHO 100
DRI OFF
FOR 100
SPR 100
DPR 100
FEI 60
In game I have FFB strength at 4 and sensitivity at 1
If you want to play around with these, mess with the FEI on the wheel or FFB strength in game. Everything else should be left alone or it will mess things up. Don't go above 5 ffb strength in game, it'll just clip. If the wheel is too strong for you, try in game ffb strength at 3 or turn FEI down to 40 or 50. If you want it stronger, try in game ffb strength 5 or FEI at 70 or 80.
Also, the current best drivehub firmware for the csw 2.5 in gt7 is the beta 8 firmware. The earlier ones have some big gt7 issues and beta 9 reportedly has a bug for some wheels. Beta 8 is the best option at the moment.
EDIT: I just reread you title. Do you have a v2.5 or v2? I might be misremembering, but I believe the DRI setting works differently between the v2 and v2.5, so if you have a v2 you might need to play around with the DRI setting too. If OFF feels weird, try at 1 or -1 and see if either are an improvement.
