Vray sun is slow to moove in viewport

V-Ray V-Ray for 3ds Max Issues
1

Hello Again,
i have something strange in my 3dsmax viewport,
If i create a teapot, a vray light or a vray cam or anything else and try to moove it somewhere else everything is super fast, but if i create a vraysun a try to moove it, everything go lagy.
when i look at the 3dsmax FPS, everything moove at something like 130 fps, while it fall to 4/5 fps for the vray sun.
i am on 3dsmax 2021 with a rtx 4090.
Have you any idea about what could do that ?
