Shader ver.: NobleRT v.1.3.3
Shader loader: iris mc1.19.4-1.6.3
Issue: when the character does not move at a maximum fps of 30, when moving, lags immediately appear with a drop in fps to 15. if we take the Seuss ptgi hrr\e12 shaders as a comparison, then it gives 60 fps stably. even when lowering the settings, the fps practically does not move from 30

Hi, SEUS PTGI and NobleRT are 2 very different shaderpacks, therefore you can't expect them to run the same way. However, I do recognize NobleRT needs some optimization, which will be done in the future.
