i can't play 4:3 resolution on full screen

Same here, playing 1280x960. mat_letterbox_aspect_goal and mat_letterbox_aspect_threshold not working anymore. Not playing until this fixed, unfortunately

how can you * this up just with some simple update, is there some other command for it now or what

yes, games unplayable on 16:9 lags like powerpoint

 Considering that there is no topic with this question in this section, I created this topic in the hope that responsible persons will pay attention to it.
On behalf of all players who are used to 4:3 resolution (stretched), I demand an explanation of the impossibility of using it after the last update, the reason for removing this feature and the answer to the question: “Will this feature be available or not, which means that the developers did it is intentional without informing the players." There was no information about this in the list of changes in the current patch. We need your answer in order to understand your attitude towards us and decide whether it is worth spending time on your product.
I ask you to join the discussion on the topic of everyone for whom it is important and who are outraged by this situation in order to finally get a full answer.
