SOLVED Radeon RX Vega 56 / Graphic glitches

[DirtyDevil]

Yesterday I played the first time on my new gpu - RX Vega 56. Before I used a RX 480 without any problem. I had the most recent driver with the RX 480 (I think 17.8.2). This is the driver for the Vegas too.

I put in my new card and it runs flawless with all tested games and benchmarks. Only with PSA (original, 1.8.4, SS, German) I got ugly stripes on the water surface. WWJD had the same problem with an old AMD gpu too. Wonder what is going on.

Anybody else got the same problem? Any suggestion to solve it? I cant play my favorite game.

I currently have an RX 480, and recently did the 17.8.2 driver update. No problems with the driver here, so far on the old RX 480 GPU, but I can't speak for a Vega 56. Hope it works out because I, too want to try the Vega on my computer.

@WWII44, Thankks for your answer. But its for notebooks to change grapchiccards btw iGPU and an dedicated GPU. Or did I miss something? I changed my GPU from RX 480 to Vega 56.

@zil: Its a good card with a lot of potential for overclocking/undervolting. I got a firestrike score above a 1080 FE with only 5 minutes fiddling with the settings - with the second bios :). If you dont mind high energy consumption I think there is a lot of more power. My min fps raised in many games and make them smother to play. And suprisingly (and to expect because of the high bandwith memory): games with big texturepacks (like Middleearth Shadow of War) load fasster. I got mine for around 400 Euros and get the key for the two games too. After I sold my RX480 to an miner at the bay its a nice deal for me :)

Back to topic: its some suprise for me that with the same driver but different hardware you get this old bug. Luckily I have a seceond GPU (a nvidia) in my pc. So I can switch to this one to play PSA. But its not the optimum :(. I hope that the next driver update solve this issue.

@DirtyDevil: Sweet! That's a real bargain, and I would be willing to pay to get some of my games running smoother. As you know, RX 480's aren't great overclockers, but I have been able to do small boosts to some games.

My dream, (and I know this sounds crazy for such an old game), is to make PSA run so smoothly, that it hardly has any lag. PSA's one of my favorite games, too and I know that goal may be impossible, (especially with so many *new* modded improvements to such an *old* graphics engine), but I still can dream. This game is one of the few that has followed me to each new computer I have gotten, and is the one I've spent the most time on, (I had the original on disc).

Thank you for your advice; I may still get a Vega, yet :)

Ok, solved the problem: under options - advanced - sea dont use pixel shaders and all works for me :)

@zile: i used the reviews for vega from hardwareluxx.de and tomshardwareguide.com for an idea for my settings. i dont have a multimeter and my powersuply is 500w / 80%. I overclock my ryzen and therefore i have to be careful with the drained power. if i had an 850w power supply i could do better scores with the card :) but i think its not worth the extra power usage. i always look for a sweet spot. if you go extreme overclocking with the vega 56 (flash vega 64-bios, p6/p7 at highest possible settings, memory overclocking, powertarget 150%) i think it will be _very_ loud with the ref fan (even if the fan can cool the card enough for the boost states) unless you use water cooling. and the power drainige would be insane. i had my rx480 underclocked/undervolted - the stock fan couldnt even hold the boost freq. so no problem with it :) .

Unluckily PSA is cpu limited and uses only one core. its too sad. all the lags cant never be worked out with this engine :(

Just ordered my Vega :^) It will be cool now to see how it handles the Total War games and mods my old card struggled with. Thanks, again!

Have fun with your new card :)

Just installed my Vega 64 graphics card, and I am very impressed. The only downside now is that I don't have audio, except for when I use headphones :-/ PSA now runs smooth(er) than before, and the jerkiness of the movements of the planes, tracers, and shells is somewhat improved. However, I did get those annoying streaks on the water, (must be an AMD thing), but I unchecked the "use pixel shader" box as mentioned before, and it leveled things out. Now, on to trying to stage epic battles!

fine, that you enjoy your new card and that you could work around the graphic bug too with the setting. i use hdmi sound via the graphic card over the displayport. works fine for me
