    Minecraft maxes out RX570

    shadowsilver

      Greetings.

       

      I've checked the forum and i saw a few other threads with an issue similar to mine, but most was on laptops with integrated graphics. and/or didn't have a resolution that worked for me. There also was one that posted his issue, but apparently never came back, but instead of stealing his thread, in case our issues aren't the same after all.

       

      First of all. You will quickly notice that all attached screenshots say "RX580", but that seems to be a bios error from Sapphire Technologies, I've seen others with the same (seemingly minor) issue. The card i have is a RX570 8GB, if you ignore the name, then the specs match Sapphires version of the card. Link to card: http://sapphirenitro.sapphiretech.com/en/570-8.html

      I used to have a AMD Radeon 7970, but it was old and started to have issues, so i recently replaced it with a brand new RX570. And all my games works fine, as expected, except for Minecraft with mods.

      When i load up Minecraft, i see that once past the main menu, and trying to join a world, either local or hosted, the GPU maxes out completely, and once ingame i have 0-1 fps.

      I've tried running the game in fullscreen or windowed mode, and that made no difference.

       

      Both Windows taskmanager, and the WattMan profiler in the Radeon settings indicate that the GPU is maxed out.

      Also, the Radeon settings where i added "javaw.exe" to be able to check it with WattMan calls it Star Wars, like seen in another thread too.

       

      The modpack version for Minecraft is one i was easily able to run with the Radeon 7970, i specific went back to the version of the pack i last played to make sure it wasn't a issue with newer versions of that pack.

      PS. Sorry if the images are a bit out of order, i had some issues with this editor

          Opened a support ticket on Sapphire's site, asking about the BIOS, and if it could cause what i'm seeing here.

              Since the 570 is basically a cut down 580 it's not really that surprising, what does Windows device manager read for the model?

               

              Normally I would recommend a different driver or game update but it sounds like you're probably up to date. Does the game run alright without any mods installed? If so, I'd suggest that something in the third party modifications package is responsible for eating up GPU resources. Perhaps something like depth of field, fog, or post processing effects...

                • Re: Minecraft maxes out RX570

                  All software reads the card as a 580, including the Radeon app that comes with the driver.

                   

                  I thought maybe it was the new driver i installed when i got the RX570, but being unable to remember what version i ran with the HD7970, i couldn't test that theory.
                  I could however swap the cards back. So, i unplugged the RX570, and plugged in the old HD7970 instead, booted up on the same driver. Started the same instance of Minecraft with all the mods. Bam. 38-40 FPS. Which is playable in my book, considering the amount of mods installed, and the limits of the Minecraft/java core.

                   

                  2018-09-26_18.03.29.png

                  So something weird is definitely going on with the RX570. While having Minecraft open, the task manager showed 37% load on the GPU, with the HD7970 that is.The mystery continues.

                   

                  PS. No answer from Sapphire yet, i included a link to this thread in my ticket. Fingers crossed

                      With the RX 570 installed, can you raise the power limit in RS and adjust the fan speed curve manually in order to achieve higher playable fps? It almost sounds like a case where the software (or BIOS) is throttling the newer card at full tilt (i.e. 100% GPU usage). HD7970 uses a lot more power than RX 570 (or RX 580 for that matter) so this might be worth checking out.

                          I'm not sure how to do that, and wouldn't it be voiding any kind of warranty to mess with these settings, just like overclocking?.

                           

                          On a side note. Sapphire support got back to me in broken English, pretty much stating they didn't care about the RX570/580 issue and closed the ticket. If they didn't make such darn good cards then i certainly wouldn't use them again.

                            • Re: Minecraft maxes out RX570

                              That's a pretty crummy response from support.

                               

                              Nevertheless, you can use the global wattman settings to raise the power limit on the card. This basically tells the card that it's alright to use more power if necessary to maintain adequate performance, so not really voiding any warranties. I typically run my cards at about +20% so that if there's something really taxing the card it is able to use more power than the default.

                               

                              This is a bit different than forcing more mV into the core, so you don't have to worry about breaking anything.

                                  Tried with +20% power in wattman. no noticeable difference ingame. Card still maxes out.

                                      According to TechPowerUP.com that has vBIOSes for all GPU Cards. The vBIOS for the RX 570 and RX 580 are identical. VGA Bios Collection | TechPowerUp .

                                          Here is how to improve the Frame Rate on your GPU card playing Minecraft: Tutorials/Improving frame rate – Official Minecraft Wiki

                                          Tutorials/Improving frame rate

                                           

                                          < Tutorials

                                           

                                           

                                          Frame rate (also known as fps) is the frequency rate at which a video device produces unique consecutive images called frames. Frames are still pictures that when sequence together form a fluid animation that is the basis for all moving media. Frame rate is most often expressed in frames per second (fps).

                                          Low fps will result in a "choppy" gaming experience, as far as looking like a slideshow in extreme cases. Difficult calculations (like blowing up large amounts of TNT or spawning in a large number of mobs) can temporarily decrease the fps to a complete stop.

                                          Monitoring frame rate[edit]

                                          Note that your displayed fps might not be accurate, as the game has to render all of the information in the debug menu, so you may get an increase as soon as you close the display.

                                          • Press F3 to bring up the Debug screen. The frame rate is shown under the Minecraft version at the top left. (Note: The debug screen is known to cause more load to your system, resulting in lower fps than you would have normally.)
                                          • Bring up the Options screen (press Esc), select Snooper Settings, and look for 'fps'.

                                          Increasing frame rate[edit]

                                          Most of the following suggestions are configurable in the game's Options menu, accessible by pressing Esc.
                                          • Turn down your render distance.
                                          • Set graphics from Fancy to Fast.
                                          • Turn off smooth lighting and clouds.
                                          • Set particles to minimal.
                                          • Set mipmap levels to minimal.
                                          • Set the game to small screen mode, as this makes the game load less on screen, making the game run a little bit faster. However for computers which have a better graphics card, change your settings, so Minecraft is in full screen mode, this makes the GPU focus more on Minecraft and less on other programs. Test both ideas and see which setting works best!
                                          • Also note, close any programs in the background and close any internet browsers.
                                          • If in multiplayer, move away from areas densely populated by players.
                                          • Enabling VBOs may result in higher fps.

                                          Outside of Minecraft[edit]

                                          • On Windows, open Task Manager and go to the processes list, find javaw.exe (the one the game uses), right click it and set its priority to high (not realtime).
                                          • Make sure you have enough RAM available (in a program such as a task manager), else your computer may swap to disk, which could cause the game to stutter intermittently.
                                          • On laptops and most pre-built desktops, uninstall bloatware.
                                          • Do not run other CPU- or GPU-intensive programs while the game is open.
                                          • On Windows Vista through Windows 10, disable graphical effects such as Windows Aero and taskbar transparency.
                                          • Disable compositing (sometimes called "desktop effects") on GNU/Linux. When compositing is disabled, all window managers tend to give similar performance, so there is no need to use a "lightweight" one.
                                          • Update graphics drivers.
                                          • Disable anti-aliasing and anisotropic filtering in your GPU driver settings.
                                          • Ensure the computer is running at a cool enough temperature so as to not cause thermal throttling. This is especially true for laptops and older desktops.
                                          • Reduce the display resolution.

                                              Hello Elstaci

                                               

                                              I've already tried most of those options in the game, but the most curious thing is that it runs fine on a 6 year old Radeon 7970, and not on a brand new RX570.

                                               

                                              As for the driver, i'm currently on the 18.9.1 driver, but i'll update to the 18.9.3.

                                               

                                              As for their vBIOS being the same, i guess that Sapphire rep i got really didn't really care, as he asked me for a zip of my vBIOS and then said that file i sent him was specificly for RX570.
