Hello Guys who likes PC Facts on this video, we will analyse what would be the best racing game of the year nothing less than the The new iteration of Forza from Turn 10 and Microsoft Studios Forza Horizon 3 The game actually, has everything to be the best racing game of the year and maybe, the best arcade racing game youy’ve ever played in your life It really has great graphics Excellent physics, gameplay Something close to a mix of simulation and arcade neither being a Need for Speed alike nor the Gran Turismo alike and the vast quantity of cars The point is that FH3 unfortunatelly has been said to be poorly optimized Is that truth? Is there any clear reason for this? That’s the point of this video: the performance analysis of Forza Horizon 3 Now comes the time to comment the performance Entrance GPUs on 720p Low Preset RX 460 with 87 FPS, much more than you might need 77fps om GTX 950, 54 on 750ti and then… guys, for this game, we would recommend 2GB of VRAM GTX 750ti of 1GB have had huge frametime problems as you can see in 1% Low and 0,1% Low measures The GPU usage is above 90% in any GPU, making these numbers to be a valid comparison Here 1080p Low Here is put a GTX 1080, that is not recommended for 1080p, but is important to have it in here to show the difference between entry level gpus and more expensive cards Nevertheless, this game engine poorly handles the gpu usage on more powerful GPUs, as youre gonna see… The best in performance results was the RX 470 with great FPS even not being a powerful GPU as a GTX 980ti… Lots of great GPUs has had a poor performance But why is that? GPU usage… GTX 1080 with 60 to 70% of usage In hardware world, 100% means 100FPS, but 65% doesn’t means quite exactly 65FPS, because of loss of efficiency What makes this comparison unffair to the greatest graphics cards Now 1080p, High Preset… There are still some unffair performance results The behavior of the GPUs shall not be taken into consideration, one more time GPU Usage, again, confirming what we told GTX 1080 60-70%, loosing efficiency… Now it’s getting better, 1440p Ultra Preset For Ultra Preset is recommended 5GB of VRAM, so NANO and RX 470 are having bad behavior… wtf GPU usage now above 90%, validating the comparison with the note that 4GB of RX 470 and Nano had made them to poorly perform Now, something that caused goosebumps on us… The Threads Usage When we see the GTX 1060 from NVIDIA And RX 470 from AMD with almost the same thread 0 usage we can safely say that it’s not a driver issue from AMD or NVIDIA but that is a Game engine error and/or in its relation with the operational system As you can see, VRAM usage on an 8GB GDDR5X Graphics card is below its limits (5,2GB) but, even so, it’s using 1,5GB of Dynamic Memory from Windows The Dynamic memory use has a great impact on cpu usage, quite heavy on CPU thread 0 And is important to add that ANY GPU is unnecessarily demmanding CPU even with free VRAM The game should allocate in the free vram of the gpu but is allocating it on the RAM of the System That’s the behavior that is causing any CPU to struggle If, even so, you’re in doubt about that because this information has been captured in 1440p Ultra (Vram bound scenario) We will show the same information captured with 1080p, low preset But before, let’s remember that some say that the problem with forza is related to encryption but, for more that it seems to make sense The Vram and Dynamic Memory issue, for us is more obvious to be the cause Even this not being the main cause to the stutter issues, it’s one of the unnecessary things that is struggling the cpu. Just think: why should you allocate 1,5 GB on 2133Mhz DDR4 If you have 2,8GB of 10000Mhz GDDR5X free and available to the system? Now, as we promissed, 1080p Low. Same behaviour, even with 8 GB DDR5 6000Mhz GPUs as 390x It’s one thing that happens in any case, doens’t matter the hardware capability you have. In this particular case, we have the 2GB RX 460 that allocates 512MB more, for trully need of Dynamic memory So, one last time. Its there. There is an unnecessary demmand for Dynamic Memory on the game engine. Everytime, any situation So, we are, pleased to have you here, and for more infos, subscribe to our channel.
