Hmm, does your video card support integer scale?
If it does I think this might be the solution for you, the video card renders the GPU image at the lower res, then did nearest neighbor scaling right before it sends it to the display. I use this daily to run 1080p on my 4K monitor so that things look crisp instead of blurry.
Here it is in the NVidia control panel, it is available I think on Turing or later cards, on ATI it is available on earlier cards I think
Mine is greyed out, it’s a GTX 1660ti, driver 511.19
It didn’t occur to me that enabling DSR would affect Retroarch at all. It seems that I need to disable this feature in Nvidia control panel, otherwise I need to force RA to use the maximum DSR resolution so it will display correctly.I think the issue wasn’t the DSR after all, and it was a strange one as I mentioned the screenshots seemed fine, but the actual output in real time was messed up. It seemed somehow related to the custom resize feature, when I install a new driver, it display a bigger area like it doesn’t detect overscan/underscan correctly, so I need to adjust it to fit my display properly. What I did was disable it and resize, DSR is still available for other games and Retroarch doesn’t seem to misbehave, so it was totally a particular setting on my end and a simple reset to fix it. I’m still not 100% sure, but after a few tests running different games that are using DSR and opening random cores/games, everything seems fine.
Unfortunately DSR doesn’t apply as other settings. When you try making a new profile for a specific game/application, DSR isn’t even listed. The way DSR works doesn’t make sense to be added as a custom setting, as the user basically tell the driver the output can be displayed at higher resolutions, once you’re inside the game configuration, you can then choose those whether you want to keep your native resolution or upscale it.
Retroarch seems to default to your desktop resolution, which in my case is 1920x1080, DSR was only “turned on” just in case I wanted to use other games with upscaled resolutions, RA was still at 1920x1080 and I could force it to use 4k but I don’t want that. It’s unrealistic seeing your GPU using almost 70% of its load in old games, doubling energy consumption without real visual improvement and taking even more time to load the shader, which is not the case in other games, if I use 4k in Sonic Racing Transformed, even on a 1080p display, the game looks fantastic, no aliasing and basically like a clean CG visual, same for GTA SA and many others, the GPU load is also around 50% or less. I explained above that the issue was fixed reseting the custom screen position, it was an isolated bug.
No, both options were tried to no avail.
Technically speaking, yes, it’s quite complex and has a lot of options. It can get quite annoying, though, as even going in and out from full screen it needs to reload, or when you’re trying different systems for other technical tests, etc. There’s no point for me to use 4K in old console games, really, it’s just unrealistic to double loading time, energy consumption and work load without real visual improvement. It would be better if you tried your own suggestions before posting, as since the first one, we’re just chatting without any real addition to the thread, no offense intended.

Hi there - first off I wanted to congratulate and thank this entire team for creating something so spectacular. The HSM Mega Bezel and all of the presets for it are truly amazing, game-changers.
I have the shaders working well on my R7 3700x/GTX 1080 rig - but I can’t seem to get them going on a SFF emulation box I have been working on.
The SFF box is a R5 2400GE apu with 16gb of 2666 ram. I believe I have everything set up correctly (again, I have it running on another computer that is right next to it) but when I load a game and then load the shader, RA just hangs. So far I’ve only tried NES - so it won’t get much more lightweight than that core. Before I go down the rabbit hole of trying to get these shaders to work, is this little machine just plain too weak for the Mega Bezel shaders? I suspect it is, but I figured I’d go to the source to ask …
Again, awesome work - loving these on my main rig.
** UPDATE: After the ADV level presets crashed RA, I tried POTATO, and it loaded (taking 2 minutes) and ran. This encouraged me to try MBZ__3__STD, as this was the least intensive option that still included reflections. It took a little longer than 2 minutes to load, and then ran. However, Nestopia only hit 50 FPS max - so the actual play experience was sludgy. Conclusion: Ryzen 5 2400GE is simply not cut out for this shader pack. For what it’s worth, it was a glorious looking 50FPS 
If it is taking two minutes to load I would make sure you are not using the DirectX video driver by mistake.
I think a Ryzen 5xxx would be the minimum. GPUs are falling in price pretty quickly anyway.
If picked up an RTX 3050 OC for under $300.
I’ll double-check just to make sure, but I did set everything to Vulkan within RA.
That said, this specific computer is a Lenovo M715Q I picked up off eBay for $250, with the intent of making a tiny and cheap computer for the sole purpose of emulation; the form factor is too small to accommodate a dedicated GPU so I think I’m just not going to be able to do these shaders on this build.
Part of the appeal of this build for me is the overall cost. At $250 for the PC, and $150 to pick up additional/faster RAM and a larger SSD, my total expenditure is $400 or less. Scouring Amazon, every mini PC in this price range is similar or worse Passmark score. If I wanted to make a material jump in performance in this form factor, I think I’d probably end up closer to $700, at which point it kind of changes the nature of the project altogether, into something much more “serious”. I’m kind of mentally thinking of this build more like a Raspberry Pi and less like a full blown PC (even though it actually is a full PC). If that makes sense
EDIT: I’ll add this - I definitely think these shaders are the future of high end emulation, so I’ll look forward to including them in the build I do for myself after this build.
I agree. I also think that as APUs mature it will be far easier to get them up and running on a budget.
Although I haven’t yet had the luxury of trying it, I have been told they run reasonably well on the $200 Nvidia Shield TV Pro. 
(I will probably pick one up one of these days.)
That’s interesting. The 2400ge in my little repurposed office box should be at least as powerful as the Shield TV Pro. Kind of makes me wonder if I am missing some kind of key setting… I’ve been goofing around with RA for a few years (on Linux, Android, and Windows) so I’m reasonably familiar with the options and configs…
Update - just tried two different presets:
Std drez gdv mini - load time above 2 mins, but ran around 54-56 fps
Std easymode - loaded in less than 30 seconds, and actually hit 59.68fps, but spending a lot of time around 58-59 fps
I’m now wondering, does anyone know what is the lightest preset that also has reflections? Obviously, I would love to have the most complex crt/scanline/image processing going on, but for me the biggest draw is the realtime reflections.
Alternatively, is there anything I can do to optimize anything else (not including frame skipping) in RA (or Windows for that matter) to pick up a couple of FPS? My BIOS does not allow processor to be OCd.
I will have to test more tonight but I feel like I’m getting closer to finding something that might be reliable and load in a reasonable amount of time.
The STD__GDV-MINI would be the fastest one with reflections.
This is super wierd, in terms of complexity of number of passes the easymode preset you mentioned is more complex than the drez gdv mini
I had loaded the drez 480 gdv mini … And that sat and sat then ran, and like I said, mid 50s. Then while that was running, I hit F1, and loaded the std_easymode (non drez).
Did the std easymode possibly load more quickly because the drez one was already loaded? I always thought when a user selected any new shader preset it loaded whatever was in that preset with no interaction to whatever was previously loaded.
Yeah, like you said what was previously loaded should not matter. But we all know how things in computers which “should” not affect something sometimes have unexpected effects
It would be good to try the non drez STD gdv mini to see what the difference is.
Ok just did some stuff:
Fresh reboot of windows and RA. Loaded STD GDV Mini. Took 2:36 to load. Ran Nestopia SMB1 at basically full 60fps. Only momentarily dropped below 59.96 fps once, and hit 60.12fps at a few points.
Closed content. Switched to Adventure Island. Loaded STD Easymode - took about 2:50 to load. Before playing, I switched presets and loaded STD GDV Mini - loaded in less than 10 seconds.
So, two takeaways: (1) STD GDV Mini does run NES at full speed on a first gen Ryzen APU and appears for sure to be lighter than Easymode or even than the STD Drez GDV Mini. (2) having another Mega Bezel shader already loaded seems to somehow speed up loading of a different preset.
I wonder what exactly is going on with my second takeaway about the load times. I also wonder if there’s any way to speed up the loading time considering the computer is apparently capable of actually running the preset.
This is definitely something which has reported a few times, I think maybe from a shield user (so it’s not just you 
) , although it’s still unexpected and unclear why it would happen.
Could you open the live log (instructions in the first post) and watch to see which part of the loading process is taking a long time?
I will try to do the logging a bit later tonight. I would love to gain some insight myself and I would love to be able to contribute in even this small way.
Thanks, this is much appreciated! Welcome to the forum and thanks for the kind words!
