Well, I was looking on first example that you post and... damn. I'm little dost. Is somehow weird that Construct - even when you set "point" of sampling method - do some pixel filtering on small objects that will show much bigger in application, so If you wanna see animations contains changing angle of object - but not only - (like in gif with exploding... heads?) you must making them (those object) bigger? I'm confused, I think I'm don't understand something here.
Here is my investigation result: Application is 640x480px with window object changing application to 1280x480px. On left you see original guy (128x128px), nothing fancy here. In the middle you see 200% of guy rendered in Construct. On right is guy 200% (256x256px) - size is changed in photoshop with nearest neighbor algorithm (something like "don't blur or sharpen my pixels, just change size of them", something like "point" sampling method should do), but most funny thing is that changing sampling method in Construct - when window object change sizes of pixels - do... nothing. I'm lost.
Sorry for the late reply, man! I don't remember receiving a notification!
I am still looking a way to solve this problem, unfortunately... My research has turned up a fix that someone came up with a few years ago. It doesn't seem to work on my computer, though. Something to do with newer graphics cards? If I could find the thread that I found the .cap from originally, I'd post that as well. Hopefully it works for you!
Either way, the quest continues!!
