Build ID: 1825438 LEDPSY (Calling pit stop) and LEDRFS (DRS zone, activation, active) did non work in this last build ID I'm not really sure that they work in the previous but i noticed it only today Thanks.
....it's all a 'private use only' F1 MOD.... where on the steering wheel we have some gauges that works fine in DX9... PIT CALL indicator and DRS Gauge and we use it since 2014... I testes it also in S-397 Silverstone 1.6 and i can confirm they don't work (I have some older screenshot that thet didn't work since first DX11 build) Thanks...
..ok.. i'm sorry... after few days i discovered that they works fine with proper texture format, DDS and not TGA. I'm very sorry... again...
