  We present a comparative analysis of photometric observations of the
cataclysmic variable TT Ari in its bright state, obtained by the TESS orbital
observatory in 2021 and 2023 and by ground-based amateur telescopes in 2022.
The light curves from 2021 and 2022 are dominated by modulations with a period
slightly shorter than the orbital one (negative superhumps), 0.13293 and
0.13273$\,$d respectively. In 2023, much stronger modulations appeared on a
much longer time scale of a few days with an amplitude of up to 0.5 mag,
compared to 0.2 mag in 2021. The negative superhump variability with the period
of 0.13376$\,$d was also found in the first half of the 2023 observations, but
then negative superhumps suddenly almost disappeared. Less significant
additional modulations with a period exceeding the orbital one (positive
superhumps) were detected in 2021 and 2022. Their periods were 0.15106 and
0.1523$\,$d, correspondingly. We also found a previously unnoticed periodic
signal corresponding to the orbital period of 0.13755$\,$d in the TESS
observations in 2021. Theoretical models of tidal precession of an elliptical
disk predict a decrease in the precession period with increasing disk radius,
which is consistent with the observed photometric behavior of the system. It
enables us to estimate the mass ratio of the components in TT$\,$Ari to be
$q\approx 0.235$. The tilted disk precession model predicts a period of nodal
precession whose value is in general agreement with observations.
