For starters, anyone who is familiar with using the upscale options in GSdx understands the improvement in image quality that it provides; there's definitely an amazing difference compared to rendering at native resolution.
However, there are games that I've come across where using upscaling seems to do the opposite. Right now, I'm examining the effect of it on God of War 2.
I'm using pcsx 0.9.7.3876 (official beta), and here are my GSdx settings:
-Native res: ON
-Alpha Hack: ON
-Texture Filtering: PARTIAL
I have the Alpha Hack enabled since the bloom layer might be distracting from my main point.
First off, here is a native-resolution screenshot (using the config above) captured using F8.
You can clearly see 'teh jaggies on the model edges -- so far, that's a good thing.
Now, if Native Res was turned OFF, but the custom resolution is still the same as the game's native res (512x448), this happens:
Major blurring on the whole screen -- a big WTF, despite the custom resolution being set to the game's native res.
Moving along, here is a screenshot of 2x upscaling:
Here, the jaggies aren't jagged at all! (upscale much?)
Here's 2x upscaling, but with Texture Filtering completely OFF.
The nature of the jaggies here indicate a few things, but the most obvious is that the screen is not being rendered higher resolution at all.
Let me say here that all the screenshots above were obtained using the F8 key -- not PrintScreen. No resizing of any kind was done in an external image editor either.
Now my question is: can GSdx be used to play God of War 2 at higher-than-native resolutions without causing upscaling or blurriness to the screen?
