Hello,

Relatively new to exploring options with DOSBox (I've been using it for ages but haven't dug into settings much and just learning about SVN options). My goal is to get ~5x scaling with HQ or BRZ or something that smooths the edges a bit these older games.

I'm using DOSBox Game Launcher 9.1 and have imported tons of my profiles already. I've got the default DB7.4 and also added DBECE as I saw that scalers for 4x-6x were available (they've been added to scaler options in DBGL)

I don't know if I should have or not, but I've added all the below resolutions to my "Dynamic Options" though few seem to work; only scaling options seem to work. I think I borked it so will need to load default values again.

I've also seend/heard/downloaded and tried xBRZ but can't seem to get it to work... what parameters do I need to set for scaling / window size to work? I've tried the following with xBRZ flavor of DB:

BRZ2x
BRZ3x
BRZ4x
BRZ5x
BRZ6x

and

2xBRZ
3xBRZ
4xBRZ
5xBRZ
6xBRZ

Neither options seem to work and can't find instructions / readme as to which options need to be set for scaler.

aforementioned Resolutions added to fullresolution and windowresolution

None of those are scalers available in Dosbox

Perhaps you already know this, but if the original resolution is above a certain limit, you have to add "forced" after the scaler option, otherwise it won't activate. And there are also hard-coded resolution limits that disable scalers and they can only be overridden by patching Dosbox.

I don't know about xBRZ or other custom-patched versions of Dosbox.

Also note that the HQ scaler is rather heavy so unless it's hardware-accelerated (or at least multithreaded) you may not achieve good performance for 5x scaling.
