I though this might be worth mentioning as I have seen quite a few questions about processor usage/stuttering/fps dropping. I had just recently built a new PC to a fairly good spec with a 10700K and a 1660S graphics card, which I was hoping would run GP4 like a hot knife through butter but it seemed to be stuttering more than than previous PC which was an 8 year old potato... The frame rate which was set to 60 would randomly drop and the frame latency kept jumping up. The processor usage would be up around 200% going down the pit straight. But then I found dgvoodoo and set it to DirectX12. Now it's like it's using all the cores (but without the crashing you get when you set it in GPxPatch). With the latest modes, FPS is a constant 60, with no stuttering, the frame latency never changes, the processor usage rarely gets to 100% even at the start - and that includes having a load of reshade filters added on top. These are my settings to get it to work.

These are a small price to pay for no stuttering, but if someone knows how to fix those bits, that would be nice!

Hello, I'm having constant crashes indeed having the CPU set to all. What settings do I need to use with dxWnd please ?]]> Hinyaldee Grand Prix 4Wed, 23 Feb 2022 14:09:28 +0100 https://www.grandprixgames.org/read.php?4,1151905,1151941#msg-1151941 https://www.grandprixgames.org/read.php?4,1151905,1151941#msg-1151941
For me (on both an amd CPU/GPU pair and an old intel/nvidia setup), dgvoodoo fixed nothing and needed a lot of tweaking to get things working, while dxWnd was almost plug and play and PO dropped tenfold. (I use it to be able to run GP3, I have no issue to run GP4 on windows 10 with recent hardware).]]> zifox Grand Prix 4Thu, 22 Jul 2021 15:02:11 +0200 https://www.grandprixgames.org/read.php?4,1151905,1151929#msg-1151929 https://www.grandprixgames.org/read.php?4,1151905,1151929#msg-1151929But I hope this helps some people.]]> fongu Grand Prix 4Thu, 22 Jul 2021 11:47:30 +0200 https://www.grandprixgames.org/read.php?4,1151905,1151926#msg-1151926 https://www.grandprixgames.org/read.php?4,1151905,1151926#msg-1151926 Turbo Lover Grand Prix 4Thu, 22 Jul 2021 10:36:56 +0200 https://www.grandprixgames.org/read.php?4,1151905,1151905#msg-1151905 https://www.grandprixgames.org/read.php?4,1151905,1151905#msg-1151905

The only problems now are that the depth filters in reshade don't work and the bright reflections, when the sun is shining directly on it, are too bright (the Environment map strength in f1graphics.cfg is only set to 8). These are a small price to pay for no stuttering, but if someone knows how to fix those bits, that would be nice!
